VBP (64-bit) doesn't terminate at end of build

[jbenson]

The build has lately been taking 5 hours on average (give or take a few minutes).

Considering your answer, do you think I somehow messed up the VBP installation? Also, I may (probably?) have logged into the VM as a different admin user account when I installed VBP than the account the build runs under. Could that be part of the issue?

I had seen in the forums other advice to kill the VBP process but I was holding off in trying that approach until exhausting all other avenues (since it seems like an ugly hack).

Thanks for the help.
