In earlier versions of VFP the HP printer drivers would muck around with the Math Co-Processor and leave it in an unsteady condition (feed it drinks and then leave). Thye following commands may cure your problems with the report crashes

Dataenvironment::beforeopentables
declare _fpreset in msvcrt20.dll	&& Force on CoProcessor if Printer driver messed with it
= _fpreset()

Dataenvironment::AfterClosetables
declare _fpreset in msvcrt20.dll	&& Force on CoProcessor if Printer driver messed with it
= _fpreset()

I hope this works for you.
