1896991 - Window freezes due to closing of Dialog button

When trying to create a comment for a row in the resultant page after executing a Web Template, a popup is shown,  you can set a comment for this row. If you click the button 'X' for closing the popup, you will come back to the report page.
Now, if you go to another row in the report page to set a new comment, then the window freezes.

If you click Ok instead of button 'X' for closing the popup which you got while trying to create comment, then it works fine.
