WinDIB didn't help

Hi guys,

Okay, so I’ve got WinDIB working - but it didn’t solve the problem that I
thought it would. Basically, I’m trying to debug a graphics problem at the
moment, but once the SGL window has lost focus, I can’t switch back - and if
I minimize anything that’s in the way then I just have a white window.

I guess it’s to do with locking and unlocking the screen surface… But it’s
just a guess. I can’t immediately see anything documented anywhere, but
that means nothing.

Any ideas as how I can fix this?
