Chem3D crashes each time I try to use it on my PowerMac.

Chem3D version 3.1.2 or earlier has trouble running in emmulation mode on the PowerMac. Chem3D 3.1.x users can download version 3.1.3 from the Files page. Otherwise you should upgrade to the latest version of Chem3D. Please note that 3.1.3 is not a native version for the PowerMac. In the meantime, Chem3D version 3.1.2 or earlier must run with the Modern Memory turned OFF. To turn Modern Memory off, go to the Apple menu, select Control Panels, and then select memory. Turn the Modern Memory off and then restart your computer.
