I'm wondering if it's related to this problem - I was able yesterday to get OpenOffice 2.3 Calc to connect un securely just by using the default port 3306 – just did that as a one time test.  

The problem I had when I did that though, was that when I open up a large table with 400 rows and maybe 25 columns in it (a table for products in an on line shopping cart), the scroll bars move through the table very slowly, and after a minute or two the table freezes up, as does OpenOffice, and I end up having to CtlAltDel and restart Open office.

>From a different desktop machine running Windows 2000 however, I am able to connect to the very same remote database using Navicat via first tunneling through port 22 SSH and then connecting to port 3306 via the SSH tunnel, and I don't have this problem, I can scroll through and edit data very fast with no crashing.  I'm wondering if the problem is with the way I have my Linux desktop configured?
