When I attempt to Start Debugging, I receive the following:
"Attached the Script debugger to process ' iexplore.exe' on machine 'MINE' failed. A debugger is already attached."
I can click OK and look at attached debug sessions -  is grayed out and there is another instance of iexplore.exe with my solution title. I can attach manually and it works fine.
I thought maybe since there were two iexplore.exe pids there would be something wrong, there are not two tabs or windows open and I disabled automatic crash recovery.
Did not work.
Please don't ask me to install VS 2012, which fixes the issue, rather try fixing the current issue with VS 2010
