On Windows 7, using taskbar icon to start MoI4betaFeb2018, or double clicking on a .3dm file, the Feb 27_2018 version does not work, although the initial version did work, and the newer version works with the if line commented out.

On regular monitor, the two menus overlap, and must be alternately selected. Both or either can be minimized.

On my 4K monitor, both Draw/Edit and Construct/Transform menus show up in full, one above the other.
(I have Scene browser placed "adjacent")
There could be room for more icons on the 4K monitor...
