I've had some similar issues.
For one, when I create a listing and enter in all the data then click next, I get BIG RED letters stating to enter a description.. what did they think that I just spent the last 20 minutes doing?
and I have been doing this for 10 years, so I do know what I'm doing.
Secondly.. sometimes when I go to look at an auction, it's blank. And I have to refresh the page to see the text.
I run Firefox on XP sp3.. bizarre.
