Toolbar Fatal error problem in AcadR14.01

[Anonymous]

I have a user running the network version on a Dell system, Win98SE,512Mb Ram and a nVidia 32Mb GeForce2 GTS video card.
Everytime he tries to customize the toolbars and even sometimes just opening up the View-Toolbars and selecting or deselecting a toolbar the program gives a Fatal Error: Unhandled Access Violation Error and one of a couple hex addresses. At that point the program closes out. Upon restart no toolbars are visible. I can copy in saved acad.mn* files to the support directory and get the toolbars back but without the customization. He really wants a resolution to this. I have tried everyting I have found in the Knowledge base but nothing seems to resolve this.

Any ideas?

Thanks for your assistance in advance!

Sincerely,

An update on the problem. It happens when the user customizes a toolbar by adding items to it. He will then exit AutoCAD and it will bomb out on the next restarts until the good acad.mn* files are copied into the support directory. No additions are made into the acad.err file on subsequent boots, so i have no lead there. The only two files that change in size from the acad.mn* are the acad.mnr (which drops to 6 bytes) and the acad.mns (only a few bytes change).

Once again Thanks! in advance for any help.
