Unity Standalone Minimizing on Windows

I've had this issue with 3 different projects on 3 different PC's now. It happens at random - usually shortly after startup, but sometimes after 30 minutes or more. For no reason (no one actively using it) the standalone player will minimise to the Windows task bar.

The player is in fullscreen mode, DirectX 10, capture single screen is unchecked. It also happens in DirectX 11, and in DX11 exclusive mode, which also causes it to hang when it loses focus.

Windows 7 32 & 64 bit, one machine with an nvidea gfx card, two with embedded graphics. Fresh windows installations - no other software installed or running.

Has anyone else experienced this?

 

I found a bit more information on this issue, so I'm posting it here in case anyone else has the same problem:

tl;dr: It's a Windows 'feature'. Use a batch script to open player as a fullscreen popup.

 

Where does the batch script get entered into?
Shell?
