In version 1.3.5, having instant preview active, the display of math

you see there some files, that generates the graphic on screen
(0lyxpreview.dvi, 0lyxpreview.metrics, 0lyxpreview.ps, 0lyxpreview.log,
0lyxpreview.tex)
In version 1.3.6, with the same equation, the only file that appears is
0lyxpreview.tex, so it means that the conversion script is either not
found or is not able to generate the needed files.
I'll send you a snapshot of the screen, having version 1.3.5 on the left
and its files in the temp directory and version 1.3.6pre in the right
side, also with the temp directory, so you can see the files generated.
I guess this is a problem of finding a script. The older version had a
lot of problems with spaces inside paths. I don't know about the new one.
It appears that you have, indeed, discovered a bug. See

description of the problem and what needs to be done to fix it.
