Nevermind. I wasn't returning 'false' after all. I was setting 'handled =
false;' but I forgot the 'return handled;'
The other compilers I use issue warnings when you forget the 'return' so I
am not used to lookng for that error on my own. I guess I should buy 'lint';
it would have saved my employer 2 days of wasted time.
Thanks,
Mark Hamann
