The weakness is Delphi. IBO's edit controls are based on the VCL
TCustomMaskEdit (and grid editing based on TInplaceEditor which is
based on TCustomMaskEdit). The VCL mask processing implemented by
TCustomMaskEdit is very limited.

My enhanced component set (mentioned by Marco) derive an entirely new
base class from TCustomEdit (TCustomEditEnh) that implements a new
enhanced mask processor that is mostly compatible with the VCL masks
but supports various modes to make the input more intuitive for the
user. The enhanced mode of input is very much like input into a
normal control, but the mask is still applied.
