RoundCube Refreshing hang

[Mat Cantin]

Greetings,

I have a weird issue with Kolab 3.2 on two separate servers. One is 
Debian with clean install of Kolab and the other is CentOS which was 
recently upgrade from 3.0. A handful of users are experience RoundCube 
hanging when it does an automatic refresh checking for new mail. It 
seems to happen especially if there is a new message that has just 
arrived. On a regular refresh without new mail, it take a good 20 
seconds, during which time the user can't click on anything.

I suspect it has something to do with the user particular RoundCube 
settings since most other users don't have this problem. I should note 
that the users how were using 3.0 only started experiencing this after 
the upgrade to 3.2. Has anyone else come across this?

Thanks.
