#===========================================================================
## 1. Add support for printf-style format specification.
## 2. Add option for repositioning on 'illegal' insertion point.
##
+## Version 1.2
+## 1. Allowed select/replace digits.
+## 2. Fixed undo to ignore grouping chars.
+##
## Version 1.1
## 1. Fixed .SetIntegerWidth() and .SetFractionWidth() functions.
## 2. Added autoSize parameter, to allow manual sizing of the control.
## nonsensical parameter methods from the control, so it will work
## properly with Boa.
## 4. Fixed allowNone bug found by user sameerc1@grandecom.net
