It does it consistantly in our installation for IE 6 on Windows.  Read a 
message or two from the mailbox.php, hit back in the browser window, and voila.

Turning off page compression fixes it.

I tried it on the demo site, but couldn't replicate it.  Is compression turned 
on?

I'm using IE 6.0.2600.0000.xpclient.010817-1148 (product ID 
55274-640-1188683-23021, update versions Q312461; Q313675) on my home machine.  
We've had some users complain about it (one of them being too politically 
powerful for us to disregard).  He was also using IE 6, tho I don't know on 
which flavor of Windows.

I was thinking about this tonight..
what about adding a browser quirk in horde/lib/Browsers.php?  
botches_compression or somesuch?  That way we could have compression turned on 
site wide, but turn it off on a browser by browser basis if we had to.  I 
wouldn't be that hard to impliment.
