>I mean if you write: "Mike of Sauk Rapids", then select "Mike", and start writing "Mr.Helland", for example.

Thats what I thought you meant, and thats what I tested before I asked, but:

lnStart		= this.SelStart
lnLength	= this.SelLength
this.value = proper( this.value )
this.SelStart	= lnStart
this.SelLength	= lnLength

Doesn't work any differently than

lnStart		= this.SelStart
this.value = proper( this.value )
this.SelStart	= lnStart

In my test
