Hello,

When I try to log through IE7, IE8 (32-bit), enter my credentials and click Login button, the browser returns me to the login page, and couldn't log me in. I try again and again, no error is returned, the credentials are OK. It happens 1 in 3-4 tries recently. I try to close and reopen the browser, try to delete browser cookies, history etc. - no effect. When I finally log in, in the Event Viewer it gives me 'Operation Success' messages (for all my tries, not only for the successful login) that the user is logged. It happens for different account, but I mostly use host account. I use 2 computers with WIndows 7 (64-bit), XP Professional (32-bit). Also I use the default MinimalExtropy template design. My DNN version is 4.9.

Please, if you don't know the exact reason, give me some clues where to look at for the unusual behavior. It's not actually an error, because no error message, nor lose of functionality i get. After I login successfully, i have no problem like a normal login. I tried to read a lot in the forum and internet about login problems but could not found any problem like mine.

I just discovered this same problem with IE 8 and 9 except I CAN login using Chrome and Safari. Three different computers with the same result.
