See attached SMath calc. There are a pair of graphs at the bottom but I can't scroll to see them. The SMath page freezes.

Any thoughts?

Thanks,

Fixed. In your definition of Pu_Mu right above you had M.u instead of M.U. Not sure why it cause a crash. But now it runs.

FYI, the way I fixed this was to disable auto calculation. Then I scrolled down and disabled evaluation of each graph. I enabled the graphs one at a time and manually recalculated each time. The left one caused the crash. When I only enabled the right graph, it produced the error showing M.u was undefined. Then I could find the bad definition from there.

Here, it does not crash but the work sheet is red from top to bottom.
