[Chimera-users] Click-and-drag selection still not working for chimera in Mac OSX....any plans for improvement

[Carmen Bayly]

Thanks Tom, Elaine,

I see - yes, my mac is from that era! Older, actually. Thanks for following
up. Shame that Apple's not maintaining an OpenGL. Do you know if the bug
disappears with newer macs?

I really appreciate this software, by the way. Showing it to all my
students!
