I have been getting crashes with "Invalid shared image reference" or words to that effect, but so far, they have eluded my attempts to reproduce them. They come after sessions in which I open a TIF file, work on it with at least 2 tools both using Real-Time Preview, save it under another name as TIF, and close it (getting the warning that although the image has not been modified since saving, there are unsaved process instances). I understand that warning, click "yes," and then occasionally get the "shared image reference" crash.
If this is not a known problem I will be glad to investigate further.
