Here is a screenshot of the bug. http://dl.dropbox.com/u/329466/ToucanBug.bmp
I was running a copy operation with no parameters. I realized that it was re-copying everything that was already there, so I canceled it at 12:21:41. That's when it said finished, then gave another error and then said finished again.
Toucan version: 3.0.3
Windows 7 x64
The job is a copy operation with retain timestamps and attributes. It is from dive s: to t: both of which are external USB drives. There is a set of rules which excludes the folder $RECYCLE.BIN.
