Crash/Freeze on clicking "More Colors" at Add Event > Change Style > Background > [Color Picker]
Steps to reproduce:
1) Select a component
2) Click "Add Event"
3) Choose interaction trigger and affected component (in this case, the click target)
4) Click "[✓] Background"
5) Activate background color picker
6) Click "More Colors" below the color grid
7) Color picker disappears, event dialog window becomes non-responsive, Justinmind window in background is still [somewhat] active, [sometimes] responding to command-Q ("Quit Justinmind" even though that menu item is currently greyed out), but Event window remains behind, must be force-quit.
