Hello!
I do experience an awkward issue:
Sometimes (not always) when I am opening the export dialog the last PDF I have exported is immediately deleted.
This can be quite frustrating whenever you have two files to export - the first one exports fine but opening the export dialog a second time (which opens in the last used directory) for the next file deletes the first one. I have to make a temp back-up of the PDF or I have to keep only one APub file in one directory. It seems that in all cases the last exported file will be deleted.
Closing or restarting does not help.
Cheers,
Chris
