The author of ClrMamePro (Roman Scherzer), said that should be "a standard 
CWin::ShowWindow(SW_HIDE) or SW_NORMAL".

I'm not so expert in MFC, but should be an MFC class, right? 
Then someone can tell me if it's known which function this function call? 
If so, I can try to debug this and also to fix it up.

Thanks in advance,
