Most of it works great but we have two small problems that i can not get 
round.
I have googled and searched mailing lists but though i can find people 
with the same problems i can find no solutions.

1)When new mail is recived there is no popup. I can confirm the the box 
is ticked and the refresh is working at 60seconds but we never get the 
notification.
2) In Internet explorer after a failed login the failee gets a blank 
screen. instead of being bounced back to the login page with the 
"Invalid Login" message.

Any help on these problems would be greatly recieved.
The rest of the system is excellent and yesterday I installed the 
phpaccelerator and that made a significant performance improvement.
