Alright, people can ignore this Mono crash and just look at the mcs one in my other email. Both XSP and mcs are experiencing the same bug it looks like and the mcs code is much simpler and easier to illustrate. Sorry for the noise. I'm just trying to bang these out since I've been sitting on them so long. Thanks.
