[Multitouch] Atom movement while still dragging #61

Closed phet-steele closed 8 years ago

  1. Finger A, manipulate either Custom Attraction slider.
  2. Finger B, manipulate the atom.
  3. Release finger A.
  4. Drag finger B to the left of the screen.

@jbphet, the sim seems to interpret step 3 as releasing the atom, not just the slider. The atom begins to move, but can simultaneously be controlled by finger B.

Assigning to @ariel-phet to decide if this should be fixed now or later. Seen on iPad Air 2 iOS 9.3.5, for phetsims/tasks/issues/693.

I think this is a "won't fix" issue. It is a rare of enough use case, and I don't think the user will be surprised that by trying two change to things at once the system is fighting itself.

Good find though @phet-steele!
