Zoho Forum in IE8

Zoho Forum in IE8

FYI...I Know that IE8 is in beta, etc.

However, just for reference, when I log into Zoho Forums in IE8, after I type in my login info, IE8 opens up another tab as soon as I click on "login" - then it opens up a third tab with the forum.

So it goes like this: I open ZForum in tab1, I type my info, click login and it opens tab2, then continues to process and finally opens tab3 with my login info. Tabs 1 & 2 are still open, but I am only logged in on Tab 3.

Weird bug.
