using a 16:10 screen at 1080p and switching to real 16:10 (1920x1200) results in a bug. it becomes impossible to click the taskbar.
I think it has to do with eViacam not recognizing the change of screen size which actually adds 60 pixels on top and bottom of the screen. this can be changed by restarting the computer.
I don't own a 16:10 screen so I cannot reproduce the exact bug, but for me works fine switching between different screen resolutions.
Which version of eViacam are you using? Which version of Windows are you using? What happens if you switch to 1920x1200 *before* running eViacam?
Another solution is the restart of eViacam.
As of version 1.6.1 you could run eViacam with the '-d' command line argument which prints many debugging messages, including the detected screen resolution. Try it to see whether resolution changes are detected properly and let us know.
For those on Windows, this can be done:
1) Press Win+R
2) Type: cmd
3) Type: cd "\Program Files\Enable Viacam\bin"
4) Type: eviacam -d
