Window hovering loses window borders or complete window

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Drag a code window by its tab (that thingie that displays the file name)

What is the expected output? What do you see instead?
Should drag a new fully-bordered code window around the screen.
Instead, the window border OR the whole window is missing until dropped 
somewhere.
Then, if dropped outside of Visual Studio, just the document is displayed and 
the document container border is missing.

Dragging around text file windows works as expected.

What version of the product are you using? On what operating system?
* ProgressiveScroll V 0.7.2
* MS Visual Studio 2012 Premium (V 11.0.60315.1)
* ReSharper V 7.1.1 C# Edition (don't know if that might collide, couldn't find 
a way to deactivate it..)
* On Windows 7 Professional SP 1

Please provide any additional information below.

My configuration of ProgressiveScroll:

Alt highlight - True
Display Border - False
Display Code - True
Display Error Marks - False
Display Splitter - True
Visible Region Opacity - 0,5
Width - 64

I attached a little foto story illustrating the bug. Careful, 7 screens of 
1920x1200 ;)

I Was able to reproduce this. It seems like a threading issue and I will have a 
fix soon.
