Just got Toucan installed and I'm very impressed. I have been wanting something to make it easy to backup my stick. One bug I have noticed is that the backup window will stop updating for periods of time. The backup is still proceeding because the backup file is still growing. It's not that big of a deal, but it's nice to see what's going on.
Also notice one other thing. When I go to do a sync using mirror I select my source and destination and click go. I see start/finished, but nothing was updated. I know that there are files updated in the folder. If I select preview first and then say yes the update works.
as for the display issue, I've noticed that myself and there are some refinements in the next version. The mirror issue is indeed a bug and will also be fixed in the next version.
