You actually need to go get to the resume page, if it screws up it kicks you back to a login.
With a little more testing, it appears to be happening in only SOME IE browsers (happening in IE 7 and 6, but only on some machines). Firefox works fine.
Here is the kicker...
Without the frame, works perfect on all browsers.
With a basic (self made) iFrame, it works perfectly on all browsers.
As soon as I put it in an iFrame in DotNetNuke. It starts screwing up as I describe.
ArGh!
Any suggestions?
