Hello everyone, I am testing LyX suitability for my thesis write-up, and I've come across an odd problem: the buttons in submenus on the maths toolbar are _mostly_ unclickable. By that I mean that the first row of the buttons in any given submenu on that palette does not work. It's hard to explain in words, so I have recorded a short video showing what works and what does not: https://vimeo.com/141471729
I'm running LyX Version 2.1.4 (24 July 2015) on OS X 10.11 (El Capitan). Please let me know if I am missing something obvious here. I've read the Tutorial and if I understood it correctly, all of these buttons should work in maths mode (and some of them do). Best regards, Ollie
