Upgraded to 6.1.1 and it consistently crashes on the second debug effort after launch. Even running 'blink' example code it will crash if I stop the first debug and then launch a second debug session. Not sure where to look to figure out what's happening. It crashes immediately - as soon as you push the debug button - so it doesn't seem to be related to the target, etc. This is on WinXP on a VM, but never had a problem with 6.01 xx
