Any luck with changing the printer driver??

>We have vfp (version 5) application that use Crystal report. With Windows 95 report works fine but with Windows NT sometime VFP crash. We can launch the same report many time (four or five times, sometimes ten times) and Crystal do the job but suddently for the same report VFP crash with memory problem.
