Yes is does. Also why would it be much faster? The app could do theredraw by blitting, which gives about the same as if the AES would doit.
The app suffers the same problem like the AES - it can't blit some backup-buffer because the content may changed, or was never fully shown (maybe overlapped by an other window, or whatever).
And there are no offscreen bitmaps with standard VDI ;)Anyway, when Helmut is sure that the rectangle list is correct when moving from one menu to another (are you?) I would like to take a third look at the issue.
