Hello all, I waste a full day with that so I put the info here. It seems that all PalmOS 4.X have a problem with the WinCopyRectangle function : if you copy from an offscreen window to whatever and that this window has been 'unlocked/unloaded' (I do not exactly what the OS does with the window but it does it...), WinCopyRectangle does not relock/reload it and try to blit so 'Fatal Error' each time.
This bug arises on Sony Cli� / Palm OS 4.X HiRes. Getting some pixels around in the bitmap (WinSetDrawBitmap' it, get a pixel, and go back to previous DrawBitmap) helps the system reload the stuff, then the WinCopyRectangle works. If anyone knows about that and has a better solution (or the reason), I'll be very happy to know. NB: I really want to use WinCopyRectangle because I want to copy a sub-part of the offscreen window.
