I'm using mac computers running firefox. When I have my bookmarks tab open the toolbar on the xmarks site overlaps, and the titles of the threads appear truncated or not at all displayed. When the bookmarks tab is disabled, (giving more real estate on the screen for the forum) the title bar displays all the functions.
The previous version of the forum would adjust the size of the screen automatically and this was never an issue. I see that there's a thread experiencing the same problems on the ipad.
I assume this is a glitch on this forum as I visit other forums running the new version of Vbulletin and do not experience this glitch.
