Beeps are my favorite debugger. They are so easy to use and I know when and where they will occur. I can't figure out the other debuggers. Anyway thanks for the help. I knew exactly where it was crashing, just could not tell why. I finally found the problem and it wasn't in the code (well, not exactly). I was trying to read an empty file and had not checked for this condition prior to reading it, thus causing the error. Thanks Mark
