On a rather unrelated note, Chimera behaves very strangely if you Hide X11 while Chimera is running. All of the pallets simply have their title bars vanish, making it very difficult to work with them. I've gotten past this by using multiple desktops, but being able to hide an application while working in another is a valuable feature, and I'd like to see the proper functionality established, if that's possible.
Tom Goddard may have already pointed out that using the yellow '-' button will iconize Chimera and hide all it's windows. If you are in the state were you've already hidden X11 and have the title-less windows showing, you can get the title bars back by unhiding X11 and using the yellow '-' button to iconize Chimera (the titleless windows are still there) and then un-iconize Chimera (the windows get their title bars back now). I've put a workaround for this behavior in our current development version and it will be in the next release. If you feel you really need it before then, I can send you instructions as to how to edit the python code (it's a one-line change).
