Behaviour seen again on 12.04.3, same texmaker, 30 January 2014. It was slightly hard to reproduce, perhaps this well help narrow it down.
Set PDFViewer to Built-in, but not embedded. Open files master.tex, chap1.tex, chap2.tex in texmaker Switch the view in texmaker to chap1.tex or master.tex Quick build, and in the Built-in non-embedded viewer of the PDF, right click and 'Click to jup to the line' then texmaker does not know that it had opened chap2.tex as the source viewer focus was not on it -- it opens a second copy, leading to errors (which copy is being saved? where did the author add text?) If however the focus was on the correct chap2.tex and you jump back to it, a duplicate copy is not opened. Aside: By the way, quick build is set to: pdflatex -synctex=1 -interaction=nonstopmode %.tex|pdflatex -synctex=1 -interaction=nonstopmode %.tex|evince %.pdf (the quickbuild configuration wizard puts "evince %.tex" when adding a the view PDF action, but it works with the built-in non-embeded viewer as configured under 'Commands' -- even when embedded it has to be set like this to refresh the embedded PDF, else the PDF does not refresh until View PDF is clicked again) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1057355 Title: texmaker opens duplicate copy of tex file when clicking jump to line using synctex To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/texmaker/+bug/1057355/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
