I have exactly the same problem: 2 OF windows on space 1, and another window on space 3.

When I check off an action in the window on space 3, the window suddenly moves to space 1, and space 1 is displayed.
(I have 4 spaces in total. Same problem when I have OF windows on spaces 2 /4 or on all of them.)
Strangely, I'm pretty sure this was broken, then it worked for some time and now the problem is backed. Still no idea what caused it.
