Hi Tom,

I changed the driver to 96.36 and it seems to work better. However,  
still the computer sometimes slow down and freezes for a while  when 
moving  a molecule (pdb: 1ii6) with the mouse. It seems to happen in  
particular when rotating the molecule with the mouse after zooming in 
(by clicking the right mouse button and moving the mouse).
