I'm unable to compare any files in VS 2012 Update 1. This is really annoying, it seems like such a basic feature and I really depend on it to review changes before checking in.
BTW - great work on TFS 2012!

I too faced the same issue. And I observed that Code Flow VS 2012 extension caused this issue. It is working fine after uninstalling/disabling the Code Flow extension.

Awesome, that worked! I didn't like that extension anyway.

Turns out that this issue is caused by an internal plugin. Disabling the plugin fixes the issue.

BTW - I'm on CORP so can use Lync to show you my desktop if you like.

Hi Craig,

Can you create a screen shot and attach it to the bug? The easiest way to do this is to hit the PrtScn button on the keyboard, paste it into Microsoft Paint and save it as a .PNG file.
