Thanks John G. ALways helpful. I specially liked your ALT-F4 auggestion. That took me back to when most people didnt know what all those Fkeys were for. That was great fun back then. Just as a helpful hint, that did indeed fix my issue temporarily.
I'll check out the ASOBO forums too. thanks. I've probably done something doofus-like, which is usually where questions like this one take me.
