Hi,
thanks, I found the reason. The problem is that the mouse wheel event
triggers the creation when getting the child control "popup". The call
creates the expensive DateChooser, which is in this case not needed.
The getChildControl method has a second parameter to trigger the
creation. To fix the issue the getChildControl call should be changed to:
var popup = this.getChildControl("popup", true); // _onMousewheel method
AbstractSelectBox
I created a bug report for this issue:

Cheers,
Chris
