Okay, what I've done is when a getText() is called inside the onChange 
handler for Combo type controls, what is returned is the text that the 
user would see in the editbox portion of the control, after the 
selection has been made. This applies for both selecting from the list 
via a mouse or up/down keys or by typing directly into the editbox.

I've also added a new routine getLastMsg() which returns the Windows 
message that caused an event handle to fire off. This is for advanced 
users as it returns the low-level {Sub/Wnd-proc procflag, iMsg, wParam, 
lParam} data. 
It allows one, for example, to differentiate between onChange getting 
fired off because the user was typing stuff or selecting stuff.
