--- Comment #2 from Ken Sharp kennybobs@o2.co.uk 2009-07-31 15:31:36 --- KERNEL32.dll.RtlCaptureContext is now implemented, but a crash still occurs.
DW20.EXE picks up the crash though. Disabling it results in the same output as clicking on "Debug"...

....so I have the feeling that's not the correct way to do things.
