Thanks! I started a new workflow. The workflow works for all the types I specified except for .tex files. When dragging a .tex file in the File Types window of this workflow, I obtain a new line "org.tug.tex TeX text file", but it does not seem to pick up any .tex files. I also tried to add the type .tex manually in the File Types Windows to no avail. It seems there is something wrong with .tex files in particular. Any idea?
