I have this at home (XP) and did the work around at work (2000). Sometimes, when I turn my computer on at home, it all works out fine. Dings, and I check it. But, sometimes, when the little soutwest icon appears it actually has a big exclamation point covering it, and when I click on it, it says there was a communication error. It never clears up. I have to turn off the computer and reboot. This has happened maybe 3 times since I got the download. Anyone know why? p.s. Just got it at work today and so far that seems to be working fine!
