[Zope] Problem modifying TinyTable data

Hi, I'm having a problem inserting data into a TinyTable. As a simple test, I created the table, clicked on it to edit it's properties, then typed an entry in the Data box. After that, I hit the change button. Nothing happened at that point. Naturally, I hit the change button again (I *could* have missed it ;-). Nothing, again. Any ideas on what could be causing this? My apologies if it's a stupid question... I'm new to Zope, but it seems that this should just work... I'm running Zope 2.4.1, with TinyTable Beta 2. (I also tried using TinyTablePlus-0.9.tgz, in case I originally got the wrong thing). It does the same thing in Konqueror and Mozilla. I'm stumped. :-( --Joel
