I have a Windows Server 2008 R2 Enterprise SP1 machine that I log into and use to manage virtual machines running on multiple Hyper-V servers on our domain. Sometimes, when I right-click on a local or remote VM, the Hyper-V Manager will crash and display the following error message:

If I use the Actions menu on the lower right, it works just fine, but for some reason right-clicking causes MMC to stop working. Is there any way to fix this issue? Here are the full details of the error message.
