There are two possible solutions:
1. get the newest MacX, version 2.0 (??) is announced/has been released.
   It provides a "backing store" for the windows.  Version 1.1.7 does not.
2. instruct the DEC software (ANSYS) you're running to keep a backing store.
   How to do that should be mentioned somewhere in its manual.

I had similar problems with IDL on the DEC: windows were not refreshed 
by MacX 1.1.7.
Fortunately, IDL has a command ("device,retain=2") which instructs IDL 
to provide a "backing store" for all windows.
Note that the X-Windows ``standard'' doesn't require the X server (MacX)
to provide the backing store.  However, most servers do, as supposedly the 
latest release of MacX.  I haven't got it yet...

Good luck,
