I've been attempting to make a model with FloorspaceJS, and all of the components work fine until I try to assign windows to the areas. What happens is after I select the window tool, I click once to assign it to a zone edge (which works) but when I try to assign the same window to another edge I am unable to. The green indicators do not appear. At that point, the model glitches so that whenever I scroll on the screen, the model follows. After deleting the window object, it returns to normal.

I have tried to remedy this by changing the window type (repeating, single, WWR) but it doesn't make a difference. Additionally, I am able to add more than one window if I change floors, but no more than one edge can be selected per floor before the model glitches again.

Any help would be greatly appreciated!
