Adobe Acrobat

I have a user that is having problems with Adobe Acrobat. When she tries to convert Word documents to a PDF file, her Vectra VL with W95 freezes up and gives her an error in the GDI.exe module, and she must reboot. Since the operation takes so long to complete, and the reboot takes place, she is able to do only 4 or 5 files a day. Does anyone know why, and if the update would help?
