Something is wrong with contour plots

Something is wrong with displaying contour plots in Mathcad 15. Everything works fine only if I create a new plot. A source file ("Contour plot_MC 2000") was created in Mathcad 2000 version. Any ideas?

Bug confirmed.

Strange thing. The area which is displayed is not adjusted to the size of the matrix.

If you increase the number of points (replace 4*... by 15*...) you begin to see something.

Could not spot any differences in the format options between the old and a newly created plot.

When I select all areas in the sheet and do a format separate regions, I get a lot of display errors like the following. The region "Injector Mass ...." would not be selectable.

The same bug occurs in Mathcad 11.0a version.

Weird, but it's not normal behavior. Did you create the file in MC2000, or did you get it from somewhere else?

I was looking for some calculations on acoustics and found the file here ("Analysis of Acoustic Model"):

Only with a huge amount of trouble. I have version 2000 on CD, but it can't coexist with later versions on te same computer.

The contour plot should not have this problem though, so I think the file must be corrupted in some way.
