[rt-users] RT 4.0.5 and IE8 very slow with the new menu

[L B]

Hi,

RT 3.8 works well on Firefox/Chrome/IE8 . RT 4.0.5 works well on
firefox/chrome but is very slow on IE8. Based on my first tests, it's
due to the menu bar present in web2 and aileron themes. RT4/IE8 works
correctly with ballard theme (which hasn't this menu bar).

Has someone already experienced this? Any idea where I can find (and
fix) the root cause?

Thanks,
