Hope this isnt covered but my search skills could not find it.

I am new to zimbra webmail and am using firefox 2. Im using the advanced version of webmail.

Sometimes when I am sent a link in an email message the link is not clickable - just grayed out. If I use the standard version it always works. If I log out and back in again it sometimes fixes itself but not always.

For example I just registered for this site and was sent the auto reply with the link to complete my registration. I could not click this link in the advanced version. I switch to the standard and can now click it. I just switched back to advanced and now the link is clickable?

Any ideas on this frustrating issue?
