Can't make more than one microscope window

If multiple microscopes are shown in connect, latest version of master will only open one window - after that, it will just change which microscope is controlled by that window

Example - opening Connect with two microscopes on the network.

Clicking to open Microber2 opens a window as expected - "Microscope window"

Clicking to open the other one doesn't open a new window, it redirects "Microscope window" to control "microscope" instead of Microber
