hpblgbe.drv

I have a user who is on a Win98 who is getting an error that keeps popping up continously. The error is:

hpblgbe.drv
Pure Virtual Function called.

Mostly this happens when she is using Excel (Office ’97 ver.). Currently she has to enter a line and save, enter a line and save, repeat, repeat, and so on. Occasionally her pc locks up and has to be rebooted. The problem seems to be getting worse. I looked on Microsoft’s KB and found nothing, does anyone here have any ideas what this error is refering to, or how to fix it.

Thanks,
Dave
