Minimizing window problems

Hello there.
There is some problems: almost every time you minimize a Total Finder window (when 2 or more tabs are opened), appears a finder window (I guess it’s one of the previously opened ones) without toolbar.
Look at the screenshot here: https://dl.dropboxusercontent.com/u/57279367/image.jpg

So, you can’t close it and it stays on desktop. To get rid of it you have to restart finder (and then load Total Finder) or - sometimes it helps - open a new finder window and then close all the tabs.

It’s pretty annoying, so I’ll appreciate any help.
