Some OS have a blank page when login

[freed1985]

there was the same problem with compatible mode enable or disable.
My IE on windows7&xp are all IE8.
But in windows7 there were no problem.It only blank in windows xp.
So I think it`s not the IE`s problem.

The other people told me ,that when he login in the panel ,there was blank.
but when he click the back buttom he can see the site ,when click other link it`s blank too.
Only can use back buttom to see the site.

There is the error report form restart httpd to visit the panel in the default-error.log.
