“Insufficient available memory to meet the expected demands of an operation at this time”

In Visual Studio 2010, When trying to copy (Ctrl + C or using Copy from Menu) i get the above error message. This is apparently a bug in VS 2010 and as of 16th June 2010 Microsoft is working on a hotfix but to ETA is yet set. See the link below:
