I dont know if its a vray or rhino’s issue but every time i click anywhere inside the frame buffer it just gets minimized without any particular reason. Its weird because in my other pc it doesnt happen.When I deleted the temp file in C:\Users…\AppData\Roaming\Chaos Group\V-Ray for Rhinoceros 5\FrameBufferState.fbs it fixed itself but after some time the problem occured again
It is a well known problem with Windows 7/8 API. It should not happen on Win10.
It is somewhat problematic to diagnose the problem, because there aren’t many win7/8 machines around here, and other pressing issues quickly take precedence. Furthermore Win 7 is long phase out by Microsoft. and any support incl. security updates will end in 6 months.
I strongly encourage you to switch to Win 10 if possible, or wait for a fix.
