Hi Stefan,

Looks nice but ...

If I start off with just the editor window open and do a TeX run, all is
well: the PDF opens, life is good. However, if I have a document with an
existing PDF and so open both, something goes wrong at the end of the
TeX run: this seems to complete but TeXworks hangs. If I get a source
file which has some (trivial) error in it, a run with the PDF viewer
closed is fine: I get the terminal error, tell TeX to continue and the
PDF then opens. However, if I then do the same run again (no changes)
TeXworks hangs before the terminal shows the line with an issue.
Something not quite right!

P.S. Any chance of Mac builds?
