[Chimera-users] Error in Windows saving a session

[Tracy Nixon]

/Thanks Eric! - I've noticed that sometimes the problem exists, and 
sometimes it does not. But it does not matter, as I am happy to rename 
the temporary file. Encountering this problem did spur me on to learn 
about making molmaps of pdb objects and then fitting mrc density maps 
into the molmap, resampling the moved mrc maps, and saving them. So the 
journey was useful!
