version 1.29.295:
It happens sometimes (not always) with secure deletion enabled.
If I click cancel, it stops running (so the program is not 'frozen')
If I run it again (same window), it will usually finish the deletion
very quickly.
I notice that there are usually some files deleted the second time,
so it is hanging somewhere in the middle of the deletion process.
I do not have this problem for the 'normal' deletion, only secure.
