David,
I installed the cvs version of preview.sty et al. without any problems.
Running latex on a "snippet" file and then grepping the resultant log file
shows:
aleem@pneumon:tmp-> grep review 1lyxpreview.log

So, I'd say that all is fine.
I don't follow your Tightpage description and certainly haven't used it to
date.
FYI, I simply take the ratio af=ascent/ (ascent + descent), where
ascent is the first number following Snippet X and descent is the number
following it. So:
Preview: Snippet 1 af=1
Preview: Snippet 2 af=0.89795918367
Preview: Snippet 3 af=1
Preview: Snippet 4 af=0.78271387611
I calculate ascent and descent info as:
ascent = af * image->getHeight();
descent = image->getHeight() - ascent;
where image->getHeight() returns the height of the image in the PPM file.
How would I use the Tightpage info in this prescription?

ps, If you're planning on releasing preview-latex 0.73 in the next week or
so, then that 's great.
