Mathcad 15 + Windows 7 + Surface Plot = NOT

[vroberts]

I have two copies of Mathcad 15, one on a Windows 7 x64 machine and another on a Windows XP machine. I tried to make a simple surface plot of three matrices and failed on the Windows 7 machine, The same file (transferred by Dropbox) works on the Windows XP machine. On the Windows 7 machine the icons on my desktop flash every few seconds when Mathcad is open and tryting to produce this graph. Does anyone know what is going on? How can Mathcad 15 be incompatible with Windows 7 after all this time?

Which property should I change? Using XP mode does not help.

OK, the trick is to right click the graph and uncheck Border. That fix was posted here two years ago! You think by now PTC would have fixed tis BUG. Why do I pay for a maintenance agreement when there is NO Maintenance.
