******BUG****** Concise problem statement: Open new schematic (blank canvas). Right click to open Context menu. Mouse cursor is then stuck to canvas so canvas slides as cursor is moved. Can't draw lines or place components. Does not happen on Chrome Version 29.0.1547.76 and Chromium Version 28.0.1500.71 on Kubuntu 12.04 LTS (28.0.1500.71-0ubuntu1.12.04.1). Don't know if this happens in Windows Firefox 24.0 (Is this related to fixing the wire break on dropped components bug report? That bug seems to be fixed in both Chrome and Chromium on Kubuntu 12.04 LTS) Steps to reproduce bug: 1. Open new schematic (blank canvas); 2. Right click (opens context menu); 3. Mouse then sticks to canvas and drags it around. Cursor slides once canvas hits edge limits. 4. Bug appears if mouse swiped to close Context menu box or, if Context menu box is left open, it slides around with the cursor. 5. Esc key does not stop behaviour.; 6. Further right clicks do not stop behaviour. Results: Mouse moves canvas rather than cursor sliding over canvas. Expected results: Mouse cursor should slide over canvas and canvas should stay put until autopan moves it near edges.
