i don't have much experience in byte compiling elisp files... nobody
seems to have answered maybe i'll take a potshot.

i tried to download and byte compile it, but first error is that i
lack the required package declared in the first line. So, we couldn't
really test it.

about this error:
> as3_elispParser.el:31515:33:Error: Invalid character: 256, #o400,
> #x100

are you using emacs 22 with emacs 23 byte code or vice versa? as you
might know, emacs 23 went utf-8 for internal char representation, so
the byte code produced are incompatible with emacs 22. The error msg
above smells like this sort of problem. If your .el files does not
have any non-ascii char, then it shouldn't be a problem though.

oh, just noticed you did give the project page link above. Am tired
atm will have maybe try later. But when did this problem start to
happen? There must be a point when things are working and not working.
