[texworks] When I typeSet the editor quit

[marsielo99 .]

Hello,

Let me thank you for the amazing LateX editor you developed.
I've only a question, why the editor automatically quit every time I
typeset? Moreover, once I typeset I'm unable to reopen the file.tex until
then I delete the pdf in the local path..
I think it's not the correct behaviour, because when I typeset I'd like to
see the preview on the right.

Best Regards,
Marcello
