Thanks for the ideas, ladies

and gentlemen! As you can see, I'm now typing in my normal verbose style.

The problem was apparently browser

related, from some kind of interaction effect I haven't isolated.

I had switched to mozilla Firefox, and

perhaps one of the Mozilla extensions interact unfavorably with the forum software, so that keystrokes aren't

registered properly. Seems most likely, anyway.

I tried the cofig and processor load things without interesting

results. I might try Oscar's idea too, just out of curiosity.

Thanks again for everyone's help. For now, I

just have to avoid using the Mozilla browser with this site.
