LabVIEW 8.0.1 stops responding during edit/save

[clark.leach]

Five times I tried to edit and save this program.  Five times LabVIEW goes brain-dead.  On page 4 of the Tab control there are 4 XY graphs.  They were initially copied from page 1 and thus showed 4 plots although I was only feeding one of them each.  I was attempting to edit these graphs thusly: 

1. change Plots shown to 1

2. change plot color to red

3. change plot line width.

After attempting to make all these changes and save the VI 4 times and getting the same negative results I decided to make the changes incrementally and see what happens.  I managed to change "plots shown" and save it; but when I then tried to make the other two changes and save it . . . brain-dead again.

I make no claims of prettiness or efficiency in this code; it is strictly exploratory at this point.

I'm running XP Pro (SP3) w/512M RAM.  This has not been an issue in the past.  I did recently install SP3 and haven't used LabVIEW a whole lot since.

Any ideas what may be going on here?

Thanks

Based on your previous experience I would wonder if the same situation is occurring, and whether you may have a hardware problem.
