I have consistently used the transparent background in chimera in the past. I have upgraded my system to Windows 7 and installed both Chimera 1.4.1 and the daily build from 9/8/2010. When I try to set the transparency to true I get the following:

Unable to turn on background transparency.

Graphics hardware supports request, but can not switch while maintaining display data.

Is there a simple solution for this?

Thank you.
