Hi,
I don’t know whether this bug has been posted already. This one is extremely annoying! When I drag a Totalfinder tab from the visor displayed on my MBP monitor (Retina) over to my external non-retina screen, Totalfinder seems to be confused, because the external screen has less dpi, I think. The Finder window inside the Totalfinder boundary is simply not re-adjusted. See the video here: https://dl.dropboxusercontent.com/u/8316393/totalfinder_bug.mov
Cheers
Felix
