To reproduce:

Cmd-Click / Right-click / Menu-click / Yellow-click on World background
	-> click to enable Show Shared Tabs (if not already)
from the Widgets tab, drag out a Paint morph
paint something
hit "keep" button on paint toolbar
try to move your new drawing (a SketchMorph) by dragging it around* while holding the Halo mouse button (middle click or scroll-wheel click or opt-click or blue-click or whatever your preference may be :) )

* note it will not let you grab it on a transparent area, so grab a painted area
