4.12 SketchViewModel has problem editing circles. I have code for drawing and editing various shapes that seemed to work fine in version 4.11. But in version 4.12, editing circles seems to be broken. When I try to drag the circle to a new location by its centerpoint, the circle remains where it was during the drag, with only a light grey square being drawn near the cursor.
When I try to stretch the circle, I don't seem to get a final completion event (i.e. state=complete) to finalize the stretching. Instead if I draw a point, then click outside the circle I get a cancel. And often during the stretch operations, the dynamics are very odd -- instead of a stretching circle I see the original circle vibrating back and forth at approximately its original size.
I think the basic logic is fine since with a simple rectangle everything works fine. but currently I'm really able to draw circles initially but not edit either location or radius existing circles.
