Making a report scrollable

You can set the report in the report execute form to be scrollable by removing the " scollable='no' " settings in CRMReports/viewer/viewer.aspx file.
The user sometimes cannot click on the "View Report" button to execute the report and scrolling the frame will give the user a method to show the button.
The settings is set on the line that creates a frame :

var oFrame = window.document.createElement ("var oFrame = window.document.createElement ("iframe name='resultFrame' id='resultFrame' src='/_root/Blank.aspx' width='100%' height='100%' scrolling='no'");");
