BUG? Sizing handles not always visible.

Since installing 7.1 the sizing handles are not alway visible.

Flipping between some jobs now and one job has selected items where the handles are visible, the other job has selections and the handles are not visible. It seems to be an intermittent issue. If you hover over where you expect the handles to be, the mouse pointer changes to the correct sizing arrows and the object can be resized.

Anyone else experience this?
