[Chimera-users] Transparent background

[Abbas]

Hi,
One feature I really appreciated about chimera was the ability to  
make pictures without a background, however recently i realized this  
is not possible anymore I checked out under the effects dialog under  
tools>viewing controls and it give me an error saying this wasn't  
supported. I haven't changed my computer since i first started using  
chimera I have updated to the latest version of chimera available for  
OSX 10.4, I wonder if this is the cause of the problem.
I would really like to have pictures without backgrounds like I used  
to, I know PyMol lets you do it, but I dislike this program. In any  
case I would greatly appreciate any help/pointers on this issue.
Thanks in advance. abbas.
