VBulletin rarely upgrade their software for cosmetic reasons ! There were sound technical reasons for upgrading - cosmestics were the last thing on their mind.
Personally I find I can get things done faster with this version than the previous.
This means it is a problem when a system is redesigned to caused a "browser issue" for a (large?) number of users. Why redesign something to cause problems for your advertisers and their customers?
The "browser issue" in every case I have seen so far (of this particular nature anyway) was solved by a simple clearing of the browser's cache/ history etc. or upgrading to the newest version.
