A few days ago, the attach button in "Attach to process" dialogue became disabled in VS 2010 and VS 2008 likewise. At first I thought that it is just an extension I've installed in VS 2010 but then I noticed it is the same in VS 2008. The both VS's a re running in administrative mode and on Windows 7. I looked around but I can't seem to find a solution to this. If anybody has encountered an similar problem, a little help would do great. Thanks upfront.
EDIT: Attached a picture of the dialogue!
Where it says
you should press 'Select' and ensure at least managed is ticked. (or choose automatic)
otherwise, the 'Attach' button will be disabled.
