Hi, I am using LyX 1.6.7, July 10, 2010 on Windows XP.
I'd like to use the instant preview feature to see xy-pic diagrams but the option to switch it on is greyed out. I have the preview package installed. The following are installed and are available from the command line: python 2.6.4.10, dvips(k) 5.98 2009, ghostscript 8.64 2009. I have called reconfigure and restarted LyX. What have I missed in my setup? All hints are much appreciated. John
