Korby Parnell posts that a new beta version of a free debugging tool from Microsoft has the ability to integrate with Visual SourceSafe (VSS). I am not familiar with this tool, but it sounds like it could be very useful for our internal debugging when we have to deal with tricky VB issues that only our testers seem to be able to reproduce.
Some of the trickiest bugs to track down have to do with timing. When you’re trying to debug in the IDE and you’re using any kind of breakpoints, this can make a bug based on a multi-threaded timing issue impossible to reproduce. This might also come in handy with debugging some of our COM+ components.
