Hi rich,
[Guesses]
Disable, as a test, third-party security, privacy, ad-blocking programs. One
of them may be causing this.

Running Ad-aware Pro? The "Block pop-ups" feature sometimes allows a window
to open momentarily before closing it.

Turn on the windows Firewall (Control Panel> Windows Firewall) and disable
(as a test) your third-party firewall.

Internet Options> Security> Internet Zone, try resetting to Default.

Search the Cookies folder and delete any cookies from that site.

If using XP, Control Panel> User Accounts> {username}> Manage network
passwords. Remove old or unused passwords or remove all saved passwords.

(Freeware) Protected Storage PassView from NirSoft:
http://www.nirsoft.net/utils/pspv.html Remove any stored passwords for that
site.
