I think I found the problem. It seems that some how there's a corrupt piece of VBA code that only shows itself in XL97. When I opened KM in XL97 here at work, I got the error, and found the piece of code. When I went to fix it on my XL2k machine, it wasn't there! I found a way around that, but don't have my latest working version here.
Everyone with the problem can hang tight and I'll hopefully get something uploaded later this evening.
