Ouch :-)
It sounds like it's something to do with your graphics drivers. Can you
check to see if you have equivalent ones before and after the change? Was
Win98 installed with a specialist driver and now you have a bog standard
one? With the PC I'm working on I get a crash if I look at a plot in a
window, as opposed to full screen! Try fiddling with your display
settings, running in dos mode and getting the latest graphics driver for
your machine. If you are low on graphics memory it may help to switch to
fewer colours or lower resolution. Also see if both 'A' and 'B' options
take the same amount of time.
The other suggestion is to avoid powplot altogether. Get hold of one of
the "alternative" gsas plotting utilities. eg DMPlot etc. Also there is a
tcldump utility within gsas which gives you an ascii file which can be fed
to a plotting program, probably via a script. Sounds like there is an
opening in the market here for something which can feed GSAS data to
something like winplotr?
Hope this helps,
Jon
