Here is the text box which has a restriction of having only numbers

Zipcode  : 

Now try to

• Enter Characters other than digits. It works as expected.
• Click after the last character in the box and press SHIFT+HOME. It should select the whole code, but it does not.


• Click after the last character in the box and press HOME. It does not take the cursor before the first character as expected.


• And even i was not able to delete the zipcode by selecting it with mouse and hit BACKSPACE key.

Any Comments .......
