Question : IE Users have to relogin

We have started testing Windows 7 and IE 8 with some users and have noticed that when they access our company website (and other sites) if the site requires a child window to open they are always prompted to re-login. These systems are clean builds with no additional Browser AddOns installed. I don't think we are doing anything special with cookies, but my gut tells me that it is cookie related and for some reason the cookie is either not being saved or it is being removed or it is not accessible via the child window.

Any advice or help diagnosing this problem is much appreciated!

Answer : IE Users have to relogin

We solved this problem by changing the "Set tab process growth" to 0. Although, we didn't have protected mode turned on and the zone was "Intranet". Evidently this is a problem with Windows 7 64Bit.
