Wondering if it was ready for primetime as I still see several bugs that existed when it was in beta form. I notice a big glaring bug which should be obvious to everyone, not just the developers @ MSFT. With multiple tabs and if you start closing them down one by one when they are trying to resize there is a huge lag before it shrinks the existing tabs once one tab is closed. IE7/8/9 do not have this lag. What was MSFT thinking?
I also still see a problem with certain forums using vBulletin 4.0 and up, where you cannot use the ENTER key as it does nothing.
this is a public peer to peer forum... we do not work for nor represent MS or the IETeam...
