(If this only happens in Win 98, I'm sure I could live with it. Just
may be helpful to report it, I hope.)

Start up R GUI, then

> plot(1:4,1:4)	# then close manually by clicking X
> plot(1:4,1:4)  # ditto
> methods(plot) 

sometimes produces normal output and even the following prompt, 
but then crashes immediately, or more often, crashes immediately with
no output.

I can do any number of plot() -methods() pairs, just not more than one
plot followed by methods(). I've tried plot x 2 followed by several other
functions without problems - methods() is the only one I know to fail.

For the above sequence the errror output is:

RGUI caused an invalid page fault in
