Yes. -- At least partly.

A lot of documents are processed without any problems. But especially
very short test files, like the one posted in this thread, have problems
at the first run when preamble caching is turned on. Then no _region_.prv
directory is created and the error message is:

error in process sentinel: unwind-protect: LaTeX found no preview images
error in process sentinel: LaTeX found no preview images

Just the files _region_.{log,pdf,tex} exist. If I then repeat
`preview-buffer' all previews are created and displayed smoothly.

Without preamble caching everything's already fine at the first run.


Maybe this problem with preamble caching has no relation to the
original problem. I remember that I always had problems with preamble
caching on that computer, so I seldom used it.
