I have a problem with FT menus not working under certain conditions.

When I keep my window wide, the menus work fine.

But this is wider than I am comfortable keeping it, and it tends to make reading difficult for me.

When I keep my window somewhat narrower, then the menus will not pull down, neither when I click nor when I hover:

This is a problem because this is the width I keep my windows.

If I make it narrower still, so that the hamburger menu button appears, then the menus work again:

But this is far too narrow.

So, Terry, I am hoping there is a way you could make the menus work for the middle width? Would be grateful if that were so, because right now the menus are not usable in my current workflow.

I'm using Pale Moon 27.6.2 on Ubuntu 14.04 LTS.
Thanks.
