Description narcís calvet 2013-11-20 10:39:01 EST 
Using attached project with Remote Desktop and remote desktop window minimized throws the error below at TTeeCanvas3D.TransferBitmap in TeCanvas.pas at line:

 {$IFOPT C+}
 Assert(tmpRes,'Error transferring internal Bitmap using BitBlt');
 {$ENDIF}
Client says: "I can reproduce the error if the remote desktop window is minimized and the program is showed normal. If this remote desktop window is in normal window state the error didn't happen. And if the program is minimized on the remote desktop and if the remote desktop is minimized, the error does not happen, too." Another client adds that in his program this error occurs directly working on the machine swithcing users,  without Remote Desktop. I could reproduce this much clearly with the 2nd project attached which records a call stack log.
According to another client this was fixed with first DelphiXE update but I could reproduce this with XE too. Compiling with assertions disabled solves the issue.
