I'm using for a popup login, which works fine except the modal will not close. The 'X' in bottom right corner, the shortcut keys, clicking on the overlay (when that box is checked in settings) - nothing closes the box. Happens in both FF and Chrome.

Update:
Found the solution from version 6.x-1.x-dev also works for this version.

Added this to css:
#frameHoverNav {
display: none !important;
}
