Hi, Paul. Could you repeat the exercise using a file name with spaces?
Disclaimer: There's something intermittent going on here, and since
intermittent can be a synonym for stochastic, I'm not sure if I've
established the pattern.
On the one hand, I tried a small test file with spaces in the name,
sitting on my desktop (which means under Docs & Sets, which means spaces
in the path as well), and the spaces did not seem to effect instant
preview.
Good. Then I'll file Eugenio's report under "unexplained user-side problem".
On the other hand, something else did. It appears that if the document
contains one or more math insets that use AMS math symbols, and if AMS
Math isn't checked in Layout | Document | Packages, then instant preview
not only won't preview the offending insets (which makes sense, since
latex should choke on the unknown symbols) but also won't preview any
insets that use plain TeX symbols. Turning on AMS Math after loading
the document is not sufficient to resolve the problem; you have to save
the document (with AMS Math selected), close and then reload the document.
On the gripping hand, opening an offending document (with AMS Math off)
and, without necessarily turning AMS Math on, editing a non-offending
formula will get it previewed (but you lose the preview if you edit it
back to its original state).
Probably. I cache results and error handling isn't really thought through
carefully.
Editing an offending formula after turning
AMS Math on will get it previewed, but again not if you edit it back to
its original state.
I think you're describing "expected" behaviour. Not necessarily how you'd
want it, but behaviour that reflects the way the thing is coded.
So maybe Eugenio's experience was confounded by this (file with no
spaces used vanilla math, file with spaces used AMS math)??
