When editing a page containing a bitmap in Acrobat Professional using the "Edit in Photoshop" button, changes are lost if the file isn't saved in some period of time (maybe 20 minutes). After this time, saving changes in Photoshop and closing the page causes all edits to be lost. Before the time, any edits in Photoshop are reflected back in the page in Acrobat.

This bug is particularly painful after spending 30 minutes cleaning up a scanned music image and having all the work lost. I've taken to doing a Select All and Copy just before closing each edited page. That way, if Acrobat times out, I can at least edit the page again and paste my work on top of the newly opened edit.

Please fix this frustrating issue.
