When I'm running an application with GameWindow and try to switch to another window I get a couple of seconds OS interface pause before the other window shows. The same thing happens when trying to get back to the GameWindow application, or minimizing/restoring it. It is more apparent when navigating with the taskbar rather than clicking on the actual window(which is impossible if you want Visual Studio/etc to be maximized). Also when starting the application it shows halfway on the taskbar and only after several seconds shows fully.
The problem is there on at least OpenTK 1.0 and 1.1 Beta 3, including the samples themselves.
I'm running Windows 7 64bit, GeForce GTX 650( on 660 Ti its the same), Visual Studio 2010.
Is this fixable?
If not, I'm willing to switch to GLControl, but would that compromise the portability to Linux and OS X?
