microsoft visual studio is waiting for an operation to complete

As usual I found the solution for this MS problem on a non-Microsoft site. The following blog post has the fix to resolve this issue:

Error: Visual Studio is waiting for an operation to complete.
By the way, I am using VS 2010. This error was first reported for VS 2005. It seems it never got fixed in the subsequent VS releases.
VS shows two options: "Switch To" and "Wait". Both offer no help.
Solution: Kill rdpclip.exe process
