Bug Report: ERROR writing Data table to SQL if multiple instances are open

This only happens if multiple instances of Duplicate Cleaner 5 are open. It won't delete and the program errors out until you close it. The bug is a little sporadic, but it shouldn't be too hard to reproduce.

Just open multiple (5-6) instances and have each instance scan separate folders. Then select the delete tab, or the Duplicate Folders tab, and you will likely get the error.

(Without knowing) my first thought is that it would be that it deals with (hash) caching?
You might try disabling that & see if you can still duplicate the issue?

If it is that, then maybe try disabling hash caching in all except 1 instance?
Or leaving hash caching enabled, but use different hash methods for each instance.


(Or I could be totally wrong here, ;-).)

Multiple instances of DC5 aren't recommended - the scan files are separate but it does use the same setting database which may lead to problems. (There is a warning). Something to look at in an update.
