Hi Andrea,
	From the bug report you also submitted I see that you only have the  
surfaces open when you do WriteDMS -- you've closed the corresponding  
structures.  Surfaces alone do not have enough information to write a  
DMS file.  The corresponding structure needs to be open so that atom  
and residue names as well as atom positions can be written into the  
DMS file.  The surface only has surface vertex positions, normals, and  
colors, which is the bulk of the DMS information but not everything  
	I find that if I open the structure you provided with your bug  
report, then do Actions->Surface->show, I can then immediately use  
WriteDMS successfully.  Let me know if this isn't the case for you.
