I have a strange issue when DF is running in that ocassionally when launching a game it will cause it lose focus when in fullscreen mode. If I close down DF entirely it resolves the issue. In DF I turned off all the bells and whistles I could find, including "Fullscreen focus" setting in Advanced Setting but the issue persists. What's annoying is that it happens maybe 3/10 times so I can't quite pinpoint the actual cause. Wondering if any experts here could chime in and give some pointers on what to check that could cause this.

Thanks.
