Works OK for me in Chrome and Firefox online. An Electron or desktop client thing?

This issue not v6.2 issue, it exited a long time, but we can't find the steps for reproduce

Well I'm not sure how you can reproduce, but a clue is that the menu with "Find Similar Objects" at the top often comes up so it looks like the mouse thinks it is over a component even though it is not, This has definitely got a lot worse  - I simply cannot work.  Can you look into it some more please.  I'm on the desktop version.  Firefox version is too clunky to use.

And another clue - if I use a three button mouse, the middle button always works correctly, but pressing left and right together doesn't do the same thing even though the usual rules are that it should.  Keeping me going for now but I hate mice with wires so please fix it properly.

"I'm on the desktop version. Firefox version is too clunky to use." * For our info: does it behave the same way in Firefox?

@andyfierman Good point.  Tried it on Firefox and it's exactly same behaviour. That said, in general the Firefox version seems a lot better than it was when I tried it about a year ago :-)

Are you sure this isn't something odd that has happened to your mouse setup? Buttons double bouncing? Battery low in your wireless mouse?

No - it's fine on every other application I use - which is loads.  This is very EasyEDA specific.

Can you help to capture a GIF for indication? I still not really understand how to reproduce

Animated GIF, if possible?

@andyfierman I seem to recall you saying here how to capture a GIF from EasyEDA but google doesn't find it.  Can you give me a link please ?
