Blank screen after login

Hi,

Blank screen issue has been discussed in other thread also but mine is little different issue. Some of my users get blank screen only on IE7 browser and after they login. Login page is secure page, after successful login they are redirected to their profile page, which is a non-secure page. Occasionally they get blank screen here with nothing on view source and there is no error. Before login, if they browse through the site, no issue with blank screen. I never saw this issue in Firefox. Any input on how to solve this will be highly appreciated.

Thanks
NK.
