I got an NPE[2] from a click, have strange actor-drag behavior (actor drags wildly / shoots off in one direction), and sometimes dots are left over on canvas at the point where I clicked on the port. Also when I'm dragging out a relation I also notice in the upper left corner of canvas a blue 'port endpoint' square (generally only noticeable in the overview section in the lower left). </div><div>See attached screenshot to see dots and blue square.</div><div>Derik</div><div><br></div><div>[1]</div><div>java.lang.NullPointerException<br><span class="Apple-tab-span"
