Not sure if this will help stu....
If i access the site by bypassing the proxy server (in which case COL can auto log me in) then i am periodically getting problems.
If i access the site via the Proxy server (in which case i have to manually log myself in) then i don't get a connection problem at all.
So is there something wrong with however COL recognises us to log us in?

Also if anyone uses AOL (and in particular their own browser software) they may encounter logging in and page not displayed errors.
Corrupt cookies may also cause problems sometimes, in IE especially, solution is to clear out IE's cache and delete any cookies (or just the COL ones if you're relying on other cookies to log you into other sites.)
It could be any number of things really
