Sorry for my late reply. I was busy for some days. Thanks for your replies.
I found this issue on FF3 on Ubuntu 8.10. Since you all cannot reproduce this problem, I tested again and found it only occurs on one particular profile of FF. I tested on other relatively clean profiles, this issue doesn't occur. Maybe it's the problem of that profile of FF, I installed many add-ons on that profile. Thank for your help. ______________________________________________________________________ css-discuss [cs...@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
