LaTeX forum ⇒ TeXworks ⇒ no .pdf in preview after \scrollmode

[MartinGeorgWeiß]

I have been using TeXWorks version 0.4.3 r.857 (MiKTeX 2.9 64-bit) on a Windows 7 64 bit system so far at my university. Now I have a new PC with Windows 10, and MiKTeX version 0.6.2 (MiKTeX 2.9.6800 64-bit).

The new version has a major drawback: When an error occurs and I type "s" to continue LaTeX, no pdf output is produced, and of course nothing is displayed. Only 100% correct files work.
When the LaTeX \scrollmode recovered after minor TeX errors in the old version, the corresponding output was displayed so I could check the rest of the document - which is much more comfortable.
The log in the new version even says "Output written on fail.pdf (1 page, 14941 bytes)." so I assume that the output is deleted on purpose afterward.

Question: is there a switch to get back the old behaviour? Settings for CTRL T are: pdfLaTeX + MakeIndex + BibTeX

Minimum working example:

\documentclass{article}
\begin{document}
Giving up is the only sure way to \fail. -- Gena Showalter
\end{document}

Sorry, but "MiKTeX Compiler Driver" did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

Partial solution: when I switch the settings in the "Typeset" menu from "pdfLaTeX + MakeIndex + BibTeX" to "pdfLaTeX" only then the .pdf is updated in the previewer after \scrollmode.
The arguments to the processing tools have changed between the two versions, with some $-variables now - but I'm not so deep into these internals.
