Hello! I've got a bug that seems to happen when either of the following happens:

You open a new WINDOW in Chrome (either from their dropdown menu, or the CTRL + N shortcut) and then close it (ALT + TAB, CTRL + W, and clicking the X in the top right of the program all cause this)

You CLOSE a Skype chat window, but ONLY when you click on the X in the top right corner of the program (pressing esc closes the program normally).

I've included screenshots as examples of these bugs:

Testing parameters:
DisplayFusion Pro on Steam 7.3 (Beta 6)
Windows 7 64-bit SP1
Google Chrome 42.0.2454.85 m
Skype version 7.8.85.102

Thank you!

Nope, and if you try to select the closed window it just closes the ALT + TAB window.
