Resize Application

I run a 3 Monitor setup … and each monitor is a different size and resolution. The problem is if I drag the ManyCam application from the main monitor (which is at 3840x2160) to a different monitor, the app does not automatically adjust for the resolution of the monitor I place it. I end up with a really large view of the application and I can not resize it. I cannot seem to control which monitor the app “thinks” it is on when it opens. Is there a way I can have the ManyCam application open on a monitor with a lower resolution so it will resize to a manageable size?

@captrosha ManyCam takes resolution from main monitor, the only way to fix is at the moment is changing your main monitor in Windows.
