I had a problem with the last several releases using minilogin.  Logging into other peoples EQ servers worked fine.  When I set up a server on my own machine, everything would work OK until I got into a zone.  At this point, the packet loss percentage would slowly climb until it hit 100% and I would then go LD.
One out of ten (or twenty?) times everything would work.
I figured it was a combination of two problems:  Not enough memory (256 MB) and too slow of a processor (450 MHz).  Some tests I ran showed EQ trying to grab 450 MB of RAM...  Playing with the datarate file didn't help me.
I got the problem to go away by using EQW!  After using EQW I haven't gone LD on log-in yet.  I'm not exactly sure why it works but it does for me...
Hope this helps someone.

P.S.  I think I remember Shawn giving this suggestion a while back but at the time I figured EQW would only make the memory problem worse.
