Hello Professor Gumm, I noticed that the url you posted is incorrect, http://www.mathematik.uni-marburg.de/~gumm/LyX/xypic.pdf
you left out the xypic directory in the url. http://www.mathematik.uni-marburg.de/~gumm/LyX/xypic/xypic.pdfAlso I noticed that in LyX1.4.0pre3 compiled with Mingw for Windows, that there are error messages and no apparent conversion
with Instant preview while converting to .dvi gives error messages. Regards, Stephen
