I'm using version 1.4.0, not sure if this is a design choice or a bug, but it defeats my purpose of having a full screen Flow Graph window on the second monitor. Steps to replicate:
1. Make Flow Graph to a floating window.
2. Manually maximize the window's width, no problem.
3. Whenever I increase the window's height over 2/3 of the screen's height, the Graph Inspector and Variables windows are displayed automatically.
