Hi,
Don't know if this is a problem specific to me...I'm running IE7 and XP SP2. Since yesterday if (and only if) I go into a thread, then press the back button nothing happens.
If I click on the little down arrow next to the back/forward buttons it shows my history as (for example)
HTTP 400 Bad Request
http://pagead2.googlesyndication.com/pa (this entry has a tick against it)
Technical Issues - Flyertalk Forums (this is the forum page I came from)
Clicking on the 3rd link takes me back to the correct place.
A little annoying. Is this specific to me? I'm logged in, and cookies are enabled.
