Sync with Folder Exclusions

Hi,
Toucan is a great tool - very useful!

I have a small issue with Syncing however. I've setup a couple folder exclusions for a particular Sync (Mirror) job and get the following error afterwards:

-----
19:09:27 Toucan 3.0.3
Operating System: Windows XP (build 2600, Service Pack 3)

19:09:27 Directory 'C:\Backup\Leuchtfeuer\Images' couldn't be deleted (error 32: the process cannot access the file because it is being used by another process.)
19:09:27 Directory 'C:\Backup\Leuchtfeuer\Import\Dialog + Atmos\OMFI MediaFiles' couldn't be deleted (error 32: the process cannot access the file because it is being used by another process.)

etc.

These are the excluded folders. The error doesn't appear on first run, only on the second/third/etc time. Rebooting clears the error temporarily.

In any case, the excluded folders are always copied to the backup folder, but they are empty at least. Otherwise, the sync job seems to work!

In case it matters, I have the following options enabled:
- File checks: File size, Modified time, Short comparison
- Retain Timestamps
- Retain Attributes
- Ignore Read-Only

Any ideas?

Thanks!
