>It was working OK yesterday. Are you saying something has just changed on UT? It's not just a matter of the initial login. I frequently drag and drop links to UT threads into a separate browser window, not necessarily one that was spawned from a login session. This only has worked when I've been able to disable the login prompt. Now, for some reason I can't turn off the login prompt, so I can't use multiple browser windows conveniently. Could there be some problem with my UT configuration, or perhaps I need to delete some cookie? (I'll try that as soon as refresh my memory as to how to do this.) Thanks for your help.

Mike,

I'm using multiple UT windows w/o any problem. My guess is, that it's something to do with your IE configuration/environment. I would delete all UT cookies, clear cache and try again.
