Subject: Failure of Surface Display

Hello,
I am trying to display a surface using the Actions > Surface>Show menu.  The surface is not displaying and the following error is in the reply:
 
C:\Program Files (x86)\Chimera\bin\mscalc.exe 1.400000 2.000000 1
Calculation of some surface components failed (code 5).
Falling back to single-component calculation.
C:\Program Files (x86)\Chimera\bin\mscalc.exe 1.400000 2.000000 0
Surface calculation failed, mscalc returned code 5
 
I am using Chimera version: production version 1 build 2540 2008/07/09
Platform is Windows Vista 64 bit.
 
The file I am working with contains 2 subunits.  If I split the two subunits into separate files and open individually in the same session, the surfaces display without any issue.  I am trying to show the surface of the two subunits associated, not the surface of each individual subunit.  Any help will be appreciated.
 
Cheers,
Chuck
