File compatibility between 32 & 64 bit

Correct me if I'm wrong, but files created in SW2008 x64SP1.0 should open just fine in SW2008 32-bit SP1.0, right?

I've run into a part which was created and opens without issue in2008 x64 on an associate's computer, but crashes my 2008 32-bitwhen I attempt to open it. Opening its associated drawing file alsoleads to a crash. I can view both the part and the drawing insolidworks explorer.

And since someone will probably ask, Though Im running XP64, I'mstuck with SW 32-bit in order to satisfy requirements for an add-inCAM package I'm using.SolidworksParts And Features
