Hi Grant,

  I fixed the Chimera problem that prevented it from starting on Mac OS 10.4
(Tiger).  It was an incompatibility between the JPEG and TIFF libraries
included with Chimera and the Mac system libraries.

  The fix is in the Chimera 1.2120 snapshot on the download page.


  Unfortunately the fixed Chimera turns up other problems on Tiger.  With
my ATI Radeon 9800 Pro graphics card Chimera crashes when a ribbon is
displayed for a molecule.  This appears to be a graphics driver bug in
Tiger.  Also molecular surfaces disappear when they are rotated.  This
appears to be another driver bug.  These problems do not occur on Mac OS 10.3
or on other platforms (Linux, Windows, SGI), nor do they occur with Radeon
9800 graphics on Windows.  We will be submitting bug reports to Apple, but
the soonest possible fix will be when Mac OS 10.4.1 comes out.

  These problems may not occur with other graphics cards, for example,
Nvidia cards.

  If you try Chimera 1.2120 with another graphics card we would like to
hear how it works (good or bad).
