Sorry. I do not read things well.
There has been changes to the above functionality in 1.3, 1.4 and 1.5
I have written it for 1.5 and have no idea if it will run on others.
Execute this and you will see 2 textboxes. type on the first one and it will
be updated in the second. I hope you are looking for this.
