No, I have over 2,000 accounts total, 1600+ are webmail users, and 
typically 4-500 connected at any given time during the work day. We 
don't encourage local clients in the organization, so most use Roundcube

I also use RC exclusively, and have for more than three years now.

Trust me, my users are whiners. If there were timeouts, I'd know. But 
I've checked the logs to verify, no session timeouts.

I'm not trying to imply there's no problem, but simply stating that 
these issues are far from universal, which would lead me to think about 
your environment.

All of my normal users are on 0.7.2-stable, but I myself am currently 
testing the latest svn in preparation for roll-out once 0.8 goes stable.

Both 0.7.2 and svn are hosted on the same server (RHEL5, Apache 2.2.3, 
PHP 5.3.3). IMAP is on a separate server (also RHEL5, sendmail, Dovecot 

I'm testing mine against both Win7/32 & Mac OS10.7, using primarily 
Safari & Firefox (on both platforms).
