Strange error that 'fixes itself' by stepping through code

I have a set of inter-twining lisp routines that, once in awhile, will throw an error "Too many arguments". If I put a breakpoint in the code and step through (without changing anything), it works fine. Why would it throw the error once, but then when I step through, all of the sudden work?

Anybody else seen this before?

Thanks,

It sounds like you have a function that is getting defined twice, requiring
a different number of arguments.

OMG, that's it. And they call me a 'professional'. HA!

Thanks Jim.
