IE 11 doesn't support position picking..

**I am trying to run the solution in IE 11… On loading the solution am getting the message like " BROWSER DOESN’T SUPPORT POSITION PICKING ". What is the alternate way, as client is particular about the IE browser. Can someone suggest how to get points on click. **

I think it should all also work fine in Edge.
