Hi, We've been using a WinSaveBits / WinRestoreBits combination to store a small area of screen that's overwritten temporarily. Fine and dandy up to this point but we'e just found a sequence of actions that produces the error:
Window68K.c, Line:92, No shadow window found This has been reported before in the forum, but without a resolution that I could see. What seems to happen, in spite of all my defensive coding efforts, is that the window handle returned gets released or corrupted somewhere between the save and the restore. The sequence involves both a change of active form (which happens elsewhere without obvious problem) and the processing of a notification. Possibly also some hi-res and 16 bit colour changes. Can anyone enlighten me on the circumstances under which that window would be released? I'm checking against multiple restores of the same handle, which was my first guess. I'm praying that it's a deliberate action by Palm OS rather than a buffer overwrite in our code...
