The entire tab-table is much tinner then in IE. But not always, it does that not on all tabs. Page 2 in the Welcometab for example is normal like it should be...When i switch to page 1 the width is 50%. I also have this with articles.
And i heard from a friend that when you switch from an tabbed article to the frontpage with tabbed content you need to press a tablink first before it shows the content.
Hope you'll fix this soon because i realy, realy like the system...
