I have VW9.5.1, running on OS 9.2.2, with USB dongle. VW randomly quits out without notification, and also sometimes decides to run in demo mode even with dongle. Machine is not on a network, iMac G4 700MHz. Only other connection is USB either iomega 250 Zip drive or Epson 1290 printer. Sometimes after printing, VW freezes. Anyone any idea? Thanks.
