Note that _this_ subset can be had from CTAN:macros/latex/contrib/supported/preview where CTAN is your favorite CTAN mirror (try finger [EMAIL PROTECTED] if you do not know about CTAN). No need to get the complete preview-latex stuff (unless you are curious). > Incidentally, if you load a document with LOTS of equations, don't expect to > see anything soon.

The good solution would be to load only those images that actually appear on-screen. Often in a single editing session, you will not even be looking at most of the document. No need to be loading the stuff into memory in the first place, then. And it sounds like thinking about some sort of persistency would be good. If you create a temporary directory with a name deriving from the main document, and you take some sort of basic timestamps from the document, it should be possible when restarting LyX to know whether one can keep the current previews or should regenerate. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum Email: [EMAIL PROTECTED]
