I assume you commented out
   self wait2ms.
in
   EventSensor >> primKbdPeek
and
   EventSensoer >> primKbdNext

this indeed has the effect that the cursor is no positioned correctly
in MVC when typing fast in an MVC workspace.

What could be the possible side effect of removing the call to
     self wait2ms

in these two methods?
