What version did you have installed previously? 3.0.3?
Is this both on the client and the server?

There is nothing in the 3.0.3 changesets that should be able to cause 
this sort of problem. Maybe it's a build or environment issue.

No. 3Mbps is not ideal, but it should be enough for running a text 
editor for sure.

Please file a ticket with more details, including log files.
There must be something broken.
