If the zoom is at the normal 100% this it what it looks like (see above). However, if you print the above it looks fine. And if you zoom the above to 125 % it looks fine.

Have you tried looking for newer versions of your video drivers?

No, I have not. I have been using this software Mathcad 14 for the past 5 yrs without any such problem. I wonder what happened to cause such a problem?

There have been many reports in the past of the symbol font getting corrupted, but this does not look like the same problem (if the symbol font is corrupted Greek characters in particular do not display right). This looks like a pure display problem, in that the characters display OK at 125% zoom, but not at 100%. You could try repairing the Mathcad installation, although I don't have much hope that will fix it.

Because it was working perfectly fine just one week ago, I think I will first try a system restore (maybe an windows update messed it up).

I finally figured out the solution to the font corruption problem!! The problem was that the Microsoft Security Update for Windows (Vista, and others) KB3013455 (MS 15-010) downloaded on Feb 11, 2015, causes 'Courier New' font corruption. This affected my Mathcad software, and my WORD software. The solution: once I removed this update, the font was no longer corrupted in both Mathcad and WORD!!!!
