Hi Stefan,

How to turn on usefull debugging? I am using ubuntu version
(0.5~t20160201~git~d4a4502~trusty1) on 14.04 and TeXworks is absolutely
unusable: hangs furing compilation. pdflatex stayes in state defunct. To be
more precise:
1. on ”clean state” only source file everything gose OK.
2. on second compilation program hangs.
3. deletingoutput file (pdf) and starting texworks — first compilation is
ok, and second fails.

The sync between source and pdf and back — does not work (when program is
opened again on comppiled source file).

Thanks and regards

PS Previous version (0.5~t20160118~git~905382e~trusty1) used to work ok
except key bindings in editor (comment, uncomment,…) clicking on a word
does not highligt it.
