VS Express 2012 occasionally hangs on win 7 64bit when closing designer windows

Question

I'm experiencing something I've never experience before. I have a new laptop and installed VS Express 2012. Everything runs great except occasionally, when I'm closing tabs - VS will just hang. It seems to only happen with WPF form design view, does not
seem to happen when closing code only windows. Everything else runs exceptionally fast. Please help, thanks.
Things to note:
cpu usage does not increase (stays at 0).
The hang time can be anywhere from 10 second to over 30 seconds (at that point i kill the process).
memory usage does not increase.
I have 3 other installations on separate computers and none of the others experience this problem with the same code. (this is the fastest computer of all of them).
The display is 4k resolution, and is the only one with that size screen.
I am not running any addons.
Basic VS installation nothing special.
I have done the following to try to fix it:
Installed all the latest plugins and patches for VS.
Installed all the latest patches for Windows 7.
Reinstalled VS on a completely seperate drive (SSD).
Erased the solution *.suo file and let it rebuild.
Disabled AntiVirus - other computers have the same AV also.
Edit for clarity:
What I mean by closing tabs - When I have my WPF project open, I will open source files inside the project and the sources file is in a tabbed window. I close the source file inside the project, either by middle mouse button or by clicking the 'x'. At no
other time have I noticed this hang and it only seems to happen when the source file includes a form design view (*.xaml) not plain text (*.cs).

Hi DMANN636,
>>when I'm closing tabs - VS will just hang. It seems to only happen with WPF form design view,does not seem to happen when closing code only windows.
Based on your issue, you mean that when you create a simple WPF project and then you get also the VS hang issue for this WPF form design view, am I right?
If yes, I suggest you could try the following command-line options with WDExpress.exe
to check the result:
/ResetSettings: Restores the IDE's default settings, optionally resets to the specified CS Settings file.
/SafeMode: Launches the IDE in safe mode to check if you install some Add-ins impact the WPF designer
If the above suggestion still could not help you, please try to delete your
ItemTemplatesCache, 
ProjectTemplatesCache folder and then run the WDExpress /InstallVSTemplates switch
and WDExpress/Setup switch. Please refer to the following steps:
Step1: Please open Windows Explorer, and navigate to <Visual Studio Installation Path>\Common7\IDE (by default is <C:\Program Files(x86) \Microsoft Visual Studio 11.0\Common7\IDE>)
Step2:  Delete the ItemTemplatesCache, ProjectTemplatesCache folder; 
Step3: Open Visual Studio Command Prompt (2012 x64 Cross Tools Command Prompt under Start menu -> All Programs -> Microsoft Visual
Studio 2012 -> Visual Studio Tools (run it with Administrator privilege: right-click the program -> Run as administrator); 
Step4: Run the WDExpress
/InstallVSTemplates switch and the WDExpress
/Setup switch.
In addition, as you said that :
>>I have 3 other installations on separate computers and none of the others experience this problem with the same code.
If you load the same WPF project on other machine, it work fine. I doubt that the issue may be related to the your machine environment. So if possible, I suggest you could try to repair or re-install the your OS would be better.
