I have been using Sumatra for many years also under Windows 10. Only recently it has started to regularly crash upon compiling a LaTeX file under TeXnicCenter. This happens quite often now, every third time, say, on the average, regardless whether there are LaTeX errors or not.
What happens is that Sumatra’s green box first shows movement, but then it changes color to red. I need to then close it. If I compile the file again, sometimes it does not crash, but often it crashes again.
I would appreciate a hint what to do.
