Time isn't the direct reason for sample apps. The main reason is to
eliminate confusion. If you post a sample app that you have confirmed
exposes the problem then I have something definitive to work with. So often
I have tried to go after a bug from scratch and wasted time floundering
because I couldn't get it to reproduce. But, I can at least give it a go and
if nothing comes up report that and we can go from there.

This sounds like a bit of a pain.

I know Chad pretty well. Have hung out with him on more than a few occasions
at conferences, etc.

I never could quite get the hang of it but once I get my D2009 release
finished up this is something I would be willing to look into.

Thanks,
