How about to try to clear browser cache?

Thanks.   Clearing the browser cache fixed it.

@UserSupport Hi, I would appreciate your help with an ongoing problem.   Its the same issue I asked about last month.  The pan feature (right click, hold and drag) which worked great, was modified a few months back in a SW release.  Now a context pop-up menu appears which almost always interferes with the pan operation.  If I am zoomed in to a layout, I can not pan at all. I assume too close to traces/parts, so context menu aperture is too large? Please let me know how to disable the context menu, on right click.  Or if there is some other way to avoid this popup?   I would like to right click and pan.  A reliable pan function is critical. Your previous suggestion to clear my browser cache improves it a bit, but it does not eliminate the problem and the problem becomes worse with time.   I'm using the Opera browser (I think its a derivative of Chrome).    I appreciate you guys have created a great tool, and it must be a mountain of work for you all.   Thanks.

If you selected a object, when you move your cursor to space and right-click menu, it will pop up the object's menu, it is a feature.

@UserSupport Hi, Thanks for your reply. I don't think you understood my question.  I'm not trying to select an object.  The problem I'm seeing is:  I can not pan around the PCB.  If I right click a blank area on the PCB, a popup menu appears. I'm not able to pan.   I don't want the popup menu because it prevents me from panning, moving around the PCB.   Preventing a user from panning can not be 'a feature'.   The product is unusable for me now.   If you can not address this issue yourself I would appreciate you escalating this internally.  I need to be able to move around the drawing.

Keep pressing right-click button or scroll button to pan. we didn't test at Opera, maybe it is different.

Hi, I logged out and logged back in using MS Edge browser.  It behaves the same as opera. I can not use the right mouse button to pan around the PCB.   At this point I believe you can not either.     I have no choice but to use the arrow buttons to move about the layout..   Using two hands instead of one hand is a is a step backwards.     Right mouse button pan has been a useful feature of the web version of your product for years?   The popup context menu is not useful to me and is a nuisance.   When laying out a board, most of my time is spent panning, zooming...  The popup menu is not used frequently, the right mouse button pan is used continuously.  Please consider a SW update so users can disable the annoying popup menu.

@M4386Z25Q, If you right-click**-and-release** then you get the right-click context menu. Left-click to exit the right-click context menu. If you right-click**-and-hold** and then move the mouse pointer, the canvas will drag with the mouse pointer. Release the right-click to exit dragging the canvas.

Hi, thanks for your reply and the details.  I know you are trying to help me. Your first paragraph.  I agree it works as you describe. Your second paragraph, it does not always operate as you describe.   Within PCB layout.   If I am zoomed in so 6 or so components are filling the screen, but there is some blank space. Left-click blank area, don't move the mouse, right-click AND HOLD, and immediately  move the mouse to pan.  What I see happening is, the pointer moves across components, sometimes 1/4 of the screen width.  I've never released the right-click.  Once the pointer touches an object the context menu appears.  Sometimes it does work exactly as you describe. I wonder if the problem is server+network latency?    I've notice when working in schematic capture, the SW is less likely to exhibit this problem.  It works mostly as you describe.  Maybe I should try the desktop client?

"Once the pointer touches an object the context menu appears." I don't see this at all. Try using Chrome or Firefox?

Only one PCB or all PCBs act like yours?

@UserSupport Hi,  The behavior is the same on all my PCBs I've edited recently.

Can you make an animated gif screenvideo and post it back here?

I'll generate one this weekend.

@M4386Z25Q, Have you tried using a different mouse in case there's a bounce on your right-click button? :)

Tried a couple of experiments.   I loaded Firefox; same problem.  (Opera, MS edge, firefox all behave same.)    Had been using a desktop system, W10, Ryzen cpu, logitec M275 optical wireless mouse (micro USB transceiver).  Is it the HW?    Tried my Lenovo E595 LT which has a logitec M570 trackball.  I find the trackball difficult to use with PCB, but I noticed pan function works.   Is it the wireless mouse?    Back to the desktop.   Replaced the M275 mouse with an old logitec wired USB, optical mouse.  The system behaves as you describe.  Massive difference.  The context menu never appears accidentally.  Right-click pan works great. Thanks for your patience.   I'm sorry the problem turned out to be my system.   I'll spend some time trying to figure out why M275 misbehaves.  I did check the mouse SW configuration weeks ago to make sure mouse functions were at default.   I'm running the logitec device SW between the mouse and the OS.  Will disable that first.     If I can get the M275 working properly, I'll post it here.

@M4386Z25Q, Glad we got to the source of the problem eventually. :)
