OK, so now I reinstalled everything not in Program Files, thinking perhaps the UAC in Vista was causing the problem. I noticed as it was installing that: checking for an HTML previewer... +checking for "firefox"... no checking for a Postscript previewer... +checking for "ghostview"... no
this seems strange since these are installed on my system...WUWT? checking for an OpenDocument/OpenOffice viewer... +checking for "oowriter"... no why not check for libreoffice? opening lyx...fingers crossed... YAY....my classes are there!! thank god for small favors!!!!
