I did some more tracing. The bad 32b VM is returning a different 
modifier bit (64 instead of 16) in the keyboard event compared to the 
good VMs. See attached pics.

Here are the steps to reproduce the problem.

  * start the image with good vm (first round) and bad vm (second round)
  * press skip
  * world menu -> workspace. Type 3+4
  * Type dispatchOnKey in search bar
  * In the method pane of the result, type "self halt" just above 
"backspace ...."
  * right click -> accept
  * select workspace and press Ctrl-p. This will throw a Halt dialog
  * select debug and click on dispatchOnKeyboardEvent (one level below)
  * right click on aKeyboardEvent in variable pane and select explore.
  * expand "buttons" slot to get the modifier bits.

The 32b VMs were run on Ubuntu 16.04 (64b) with 32b compat libraries. I 
don't have access to a native 32b linux.
