To do it interactively, in the textBox InteractiveChange:

local lnStart, lnLenght

lnStart		= this.SelStart
lnLength	= this.SelLength

this.value = proper( this.value )

this.SelStart	= lnStart
this.SelLength	= lnLength

The SelStart thing is because every time you reassign the value, otherwise, the cursor gets again to the start of the field.
