Bug report MacOS8.6

[JamesWColes]

I get this error as recorded in the log file when I run VNC Viewer PPC:

Vnc Viewer starts 22:58:55 on 10/06/2002

Started connection number 6aa55a4 to 7600 on display 0 at 22:58:58 
Connection 6aa55a4 throws an error: T_DNRSTRINGTOADDRCOMPLETE fails -3150 
kOTBadAddressErr - A Bad address was specified
Connection 6aa55a4 closes  at 22:59:1 

FYI My machine is a 7600 running MacOS8.6 with 160MB RAM and a 180MHz 
604e processor.  The other machines on my network are a Windoze  98 PC 
-which is running VNC Server and a Smoothwall proxy server. The Mac is 
hooked on to the Network via Thursby DAVE software.

Any ideas as to how I can fix this?
