Issue I have two monitors (1920X1080 on both) and the extension works only on the edges of the left monitor.

[icarter09]

@brub2 does this issue only occur when there are two monitors involved?

No error log. Expected behaviour: Working on all screens. Actual behaviour: Only working on the left most screen, even if this is not the primary screen. Seems other screens get ignored completely.

I have the same problem. The extension is working on left monitor (not primary) and is not working right monitor (primary) with no error in log. On the other hand, the competing extension "Desktop Scroller" is working fine.

I see the same problem on mine. I have 3 side-by-side, with the Middle as the primary.

I think the problem is the Area defined to listen to the events is defined as x=cornerSize; dx=monitor.width - cornerSize*2; but the monitor width is ONLY the primary monitor's width. All of my monitors are the same size, but, I believe it means the area doesn't cover the other desktop's bottom edge.

Surely for 3 monitors side-by-side, For an area across ALL of the monitors, you would want: x=cornerSize; dx= 3monitor.width - cornerSize2;

Alternatively, for the area on ONLY the primary monitor, you want: x=cornerSize + monitor.left_offset; // whatever this is actually called - the left most pixel's coordinate dx= monitor.width - cornerSize*2;

This also applies to the corners... it only creates the areas on the left monitor, it should perhaps create those areas/corners for EACH of the monitors. OR it should offset their origins (x,y) to where the primary monitor's origin is.

I want to hack this and see if I can fix the bug... where is all the documentation on the imports.ui.main API and stuff like that ? There are no obvious resources for helping me to start hacking ...
