Removing the creation of calendar entry by clicking on blank section of calendar?

Hello All

We are using IP2015 15.6.0.0 Application and when we go to Calendar screen, we can create new record entry from + icon. However in OpenUI, we can create new entry via clicking on blank section of the calendar and It will open a Popup, ask for description and when we press OK, it creates a new calendar entry.

Screenshot:

This is Siebel Vanilla functionality and it is present in jqfullcalrenderer.js file.

In that, if we remove following code from jqfullcalrenderer.js file then this functionality gets removed.:

  e.prototype.BuildQuickAddDialog = function (f, i) {

  var h = this.GetPM();

  var s = this.GetCalCtrlEventHandlers();
