The number of things that can go wrong in windows is unlimited, I think. In my case, if the LyX Preview->PPM converter is defined as python $$s/scripts/lyxpreview2ppm.py then instant preview fails and in the terminal I see the message Could not fork: No such file or directory But if it is defined as python.exe $$s/scripts/lyxpreview2ppm.py then everything goes well. Moreover, if leave untouched the definition and create a python.bat script (ahead in the path) which simply calls python.exe, again everything is ok. This really is beyond me. Another cause of failure for me (but not always) is that I also have pplatex and it is picked first by lyxpreview2ppm.py. I had to tweak the script such that latex comes first... -- Enrico
