After placing the custom view outline onto the design board any subsequent objects ( label etc.) are difficult to place into the design area as the board "moves" ahead of the object. This seems to occur 1 to 2 out of 3 times when using custom views. I am not sure how to replicate as it is an inconsistent bug.
For example at the moment the custom view works fine but yesterday I was chasing it all day.
