9034	IE: Unspecified Error when making a selection in the editor	Teresa Monahan	Garry Yao	"An 'Unspecified Error' is sometimes thrown when selecting text in the editor. We cannot reproduce this in a standalone testcase, however it happens very often in our application. It happens in IE8 and IE9 when run in IE7 document mode.

The issue happens when you select text by starting the selection at the end of the editor. We believe this is related to the following code in the selection plugin which handles the case where the user clicks below the body.

{{{
function onHover( evt )
{
	evt = evt.data.$;
	if ( textRng )
	{
		// Read the current cursor.
		var rngEnd = body.$.createTextRange();
		rngEnd.moveToPoint( evt.x, evt.y );

		// Handle drag directions.
		textRng.setEndPoint(
			textRng.compareEndPoints( 'StartToStart', rngEnd ) < 0 ?
			'EndToEnd' :
			'StartToStart',
			rngEnd );

		// Update selection with new range.
		textRng.select();
	}
}
}}}

Adding a try/catch around this code as in the attached patch seems to fix this issue. Can you see any undesired consequences of this patch?"	Bug	closed	Normal	CKEditor 3.6.4	Core : Selection	3.6.3	fixed	IE7	Damian Satya Minnekanti
