On my LyX2.1.4-Win7 install, if I only change a menu setting, LyX will NOT re-typeset the document to reflect the changes when <View> is selected. I have to type something in the body or preamble to force LyX to re-typeset! it simply shows the previous pdf.
This has caused me hours of confusion debugging things that do not work with LyX. It is inconsistent and unintuitive. Before I lodge a bug-fix can someone confirm it is not just limited to my install please Any explanation or fixes gratefully accepted.
