[R] dev.off() prematurely stops xyplot()

[Waichler, Scott R]

I have a script containing an xyplot() to print to a postscript
file, followed by dev.off().  When I source the script, the dev.off()
seems to cut off the xyplot() execution before it is finished.  
The resulting postscript file has about the right size, but it 
appears blank when I try to view it.  If I manually execute the
xyplot(), then wait for the return of the R prompt before executing
dev.off(), I have no problems.  Can someone help?
