I found another reason to not use FireFox. For whatever reason, it doesn't play well with my tablet PC. Fields are just not showing up as being editable. Too bad, too. After downloading 1.0, I decided that it was, in fact, a signifacant improvement over 0.9. If I could get it to work with my pen, I'd probably give it a fair shake.
As for Trillian, I'm not real impressed by the latest release, either. I'm having problems with auto-connecting and it seems to be manhandling my power-management. Which is to say, I've had problems with the screen-saver not kicking in and the monitor not powering down, etc. since upgrading.
