[Chimera-users] Chimera for Mac 10.7

Hi Chimera Team, Which version of Chimera do you recommend I download in order to use for Mac 10.7? I downloaded chimera-1.5.3-mac.dmg<http://plato.cgl.ucsf.edu/chimera/cgi-bin/secure/chimera-get.py?file=mac/chimera-1.5.3-mac.dmg>. Although it opens, I cannot use any of the features such as any of the actions or presets. Thank you, Michael
