Jetadmin / Word 97 / Novell Problem

1) Network with WIndows 95 workstations & Netware 4.1 or Microsoft client for Netware.
2) Problem occurs only on machines with HP JetAdmin
3) Error—> MDREXE caused an unexpected page fault in module HPDMIPX.HPA with a stack dump but I don’t haveit currently.
4) Error occurs after initial log on to the network (about 5-10 seconds in)
5) If I un-install Jetadmin immediately after logon reboot and re-install the error ceases EXCEPT
6) On workstations with Office it seems to have affected something in that Word will hang only on starting from the toolbar. It’ll start fine from the start menu.

ALL of these problems happened at once. Are they linked—what caused them and is there a fix.
