Hi,
	We have run into a bug while using Parcplace rel. 4.0
smalltalk-80 running on the HP9000 -series workstations (330/350).
The bug arises when using the message follow: while: on: ,
usedn essentially to animate display stuff on a GraphicsContext.
Using this message on the HP platforms causes a primitive error.
This message works fine on the other platforms, 386 based machines,
and Sun workstations. BTW, we running X11.
Has anyone else encountered this problem, and know of possible
fixes ?
thanks,
	-- Brian
