today I found that trying to move an issue in JAC that when transitioning through the screens "Select project and type", "select new state", "update fields", "confirmation" that after clicking "Next" once, on the second screen the "Next" button becomes highlighted as though the text cursor is blinking to the left of the button. The button also becomes un-clickable.

A quick work around is to change tabs in safari, after transitioning back to JAC the next button is again clickable.

Selecting other text on the screen is also impossible, so not useful as a work around
