I have multiple panels in designer, each panel has various other views on them.
I right clicked on a view, I duplicated it and then accidentally dragged the new view onto an area that has no views on it and dropped it and it disappeared, now every time I try and create a new view it B4A crashes....
I had an issue when i duplicated a view (i believe it was a panel within a panel) and it didn't stay in the same parent as the original view, the kicker was when i tried to drag it to it's rightful owner i got some kind of error msg and i couldn't get it to go to the right parent, even in the properties window. I finally just deleted it and did add new view.
