Instant preview does not work for lyx 2.0.1 for OSX

[Marcus Kriele]

Instant preview does not seem to work with the 2.0.1 cocoa binary for 
Mac OSX.  I have re-downloaded the last 2.0.0 version of the binary and 
instant preview works flawlessly with this older version.  Therefore my 
problem does not seem to be caused by my lyx settings, unless I missed a 
change of lyx settings which would be required for 2.0.1.
