Client Not Active in Process Errors

[mplayer254]

I have noticed that while trying to connect to my server through my Vista PC, I am consistently getting an error message that says Client Disconnected: Client not active in process (in World.exe). The error always occurs when I attempt to enter (any) zone from character select. I have never received this message on the XP desktop and laptop I usually log in on and was just wondering if anyone else has seen this? I did a search but without being able to search for that specific phrase I could not find any threads that seem to tackle the issue. It is a minor bug which could just be Vista specific but I thought I would see if anyone else was having the issue. I run CD's PEQ Pack w/ latest Update Pack (1129 rev 89) and Revision 201 from the google downloads for Windows binaries (sql's have been sourced in).
