I'm running OSX Yosemite and using JetBrains IntelliJ 2016.2.3.
I can't resize the IDE window, except for the maximize or minimize buttons. What I want to do is use the mouse to stretch the borders of the window to make it smaller or larger. But as I hover my mouse over the borders or corners of the IntelliJ window, the cursor does not change and I can't grab the edge of the window at all.
Every other application window on this Macbook supports resizing normally, but somehow IntelliJ doesn't.
Strangely, I also run on the same Macbook JetBrains PhpStorm—another IDE product from the same company—and that window does support window-edge resizing.
I've read about some add-on products for OSX that assist in window resizing, but I'd prefer not to install a tool. This should work with plain OSX, shouldn't it?
