IE8 and IE9 support about rangyinputs

[timdown]

This is almost certainly because you're doing this in a click (or similar) handler on a buttton that has stolen focus from your textarea or input and destroyed the selection by the time the click event fires. You can work around this by using mousedown instead, or by making the button unselectable.

Thanks a lot Tim. What you have mentioned above is what is happening in my case. Thanks for your time.
