Ah, ok. This is indeed a new and puzzling behavior and looks like a 
bug. The MaskBox of the current Gambas Stable doesn't do this.

A Zero seems to tell the algorithm that no digit was entered at the 
current position (although is was). To me everything would be fine if a 
Zero would be regarded like any other number.
