Are you calling MouseHelper.setFunctionMap()?
Or MouseHelper.setEnableCombos()? Or are you
using a custom extension of MouseBehavior?
These are the only way I know to modify mouse
button behaviors. If you've found a bug, we've
never seen this sort of thing before (which
doesn't mean its impossible).

How are you excluding points? By actually
constructing new Fields with those points
removed? Or merely by SelectRangeWidgets?
