[Chimera-users] edges

[Elaine Meng]

Hi Vincent,
Maybe you are referring to "silhouette edges" - these are absolutely  
controllable, however, either by choosing a Preset that does or does  
not include them (from the Presets menu) or by opening the Effects  
tool  (under Tools... Viewing Controls) and turning them on or off.

That seems the most likely to me.  Otherwise, I have no idea why  
black edges might appear in the interactive Chimera display (graphics  
driver bug?).
I hope this helps,
Elaine
