Hi Pete.
No. Exactly as described.
CopyRect, then Flip. No other complication.
I've also tried as an experiment inserting UpdateWorld + RenderWorld then Flip, and 'cause I'm going thru line-by-line in debug mode I can see, as expected, the BackBuffer moved to the FrontBuffer just fine.
It's simply as if CopyRect fails when used between the two Blitz system buffers.
