After installing V1.2.3 I noticed that the Add Location button in the Share box now has the Add Location Tooltip text unglued and showing in the Share box.
If I click on the Location Icon or the Add Location tooltip text with the link the cycling cursor issue appears. I have to click the close box to get it to stop cycling.
