Someone else recently asked for something along these lines. Its
obviously a feature I need to investigate. I like your suggestion to
use the eeoAllowEmptyExit option to control this.

eeoAllowEmptyExit is currently only used for controls that have masks.
So one way you can achieve your requirement immediately is to apply a
mask with mandatory input positions (eg: "::EM::Ccccccccc;0;_" with as
many 'c's as required to support your input) and set eeoAllowEmptyExit
to false.

Meanwhile I will investigate the option of using eeoAllowEmptyExit to
also control exit from combo styled controls. Thanks for the idea :-)
