Glad to hear I've done something "interesting"!

I looked/tried the test program and it's essentially what I've done.  The problem is that you don't see the "writeline" statements until you toggle back to change the values again.  If you write to the console as you're updating the sprite you can't view any messages you've written to the console at the same time you're looking at how the sprite was affected by the updates.  BTW.. I know I can accomplish this by simply outputting the messages using Trace().

I stumbled into the question while trying to create a more interactive debugger for positioning & transformation methods that were going awry.  I was hoping to be able to alter the sprite values at certain points without having to start/stop the program (a step towards the flexibility you have in other debuggers).

Before I went down the toggle path and rethink my strategy I thought I'd ask the obvious question.  At this point I think we can consider the question closed unless someone comes out with another scenario that would require both views to be present at the same time.

Thanks!
