CLR has been unable to transition from COM context for 60 seconds

Error Message:
"The CLR has been unable to transition from COM context 0x197060 to COM context 0x196ef0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."

Solution:
1) I've read a few things about a config file, but I couldn't get this to work reliably. Instead, you can switch the MDA off by going to:  Debug -> Exceptions -> Managed Debug Assistants and unchecking the ContextSwitchDeadlock item.

2) Don't see that option?  Then you may have SP1 in Visual Studio 2005.  To activate the window use this shortcut:  "Ctrl-Alt-E" opens the window"
