This is not a "Suggestion", this is a "BUG".

I am running OSX El Capitan, 10.11.6, although this has also been verified by co-workers running OSX Sierra.

After updating to HipChat Version 4.30.1.748, the HipChat window cannot be moved; it's "glued" to the same location on the screen.  I select the title bar and drag - as in any other OSX application - but nothing happens.  It can be resized but not moved.  I have even completely quit HipChat and restarted, with no effect.

When clicking to drag, I notice the icon changes to a text edit "beam", whereas it should remain as an arrow to indicate dragging is possible.
