I've just received the 6.1 update and the Layout designer doesn't seem to be working. I've deleted my entire Android layout and when I try to add a GridLayout onto the canvas or onto the outline window as soon as I drag the control out of the Toolbox it disappears and I can't therefore make the alteration.
The designer wasn't working very well in previous versions, but it's now totally useless.
Is anyone else having this problem?
If I'm not alone in this than this is a worrying sign of poor quality control.
