What are you debugging?
Is it something complex or a simple test project you can provide, so I can test too?
I've not tested it thoroughly on windows.
I've done a simple test and it stopped on the breakpoint (I think).
Do you see the breakpoint in the breakpoints dialog and do you see the break commands in the "debugger log (debug)" window?
Does "run to cursor" work.
"Evaluate expression" doesn't crash here, if you provide an example project I'll see what's doing on.
