Blinking Cursor Issue

For some reason or another I can't seem to get the cursor to blink...   the setup is as follows

Inside of a class I create a selectionmanager, and an editmanager on instantaition of the class.  I build the text flow, and then assign the interaction manager of the textflow to be the editmanager.  I then  start coloring portions of the document with the editmanagers settextformat, once coloring is complete i set the interaction manager back to the pre constructed selectionmanager.   Under this scenario the cursor never blinks whenever i click into the document. 

I get no blinking love even after setting the selection formats via:

var objSelectionFormat:SelectionFormat = new SelectionFormat(0xFFFFFF, 1, BlendMode.DIFFERENCE, 0xFFFFFF, 1, BlendMode.DIFFERENCE, 300);

_objSelectionManager.focusedSelectionFormat = objSelectionFormat;

_objSelectionManager.unfocusedSelectionFormat = objSelectionFormat;

any ideas?

For a little more info, inside the coloring routine I am am applying a textformat to the entire document with a transparent background, and coloring portions of the text with this method:

public static function SetRegionColor(objFlow:TextFlow, iStart:int, iEnd:int, iBackgroundColor:*, nBgAlpha:Number = 1):void

{

var objFormat:TextLayoutFormat = new TextLayoutFormat();

objFormat.backgroundColor = iBackgroundColor;

objFormat.backgroundAlpha = nBgAlpha;

var objSelection:SelectionState = new SelectionState(objFlow, iStart, iEnd);

if(objFlow.interactionManager == null || objFlow.interactionManager is EditManager == true)

{

var objManager:EditManager =  objFlow.interactionManager as EditManager;

objManager.applyFormat(objFormat, objFormat, objFormat, objSelection);

}

else

{

throw new Error("TextFlow is Not Editable");

}

}

Also, if i leave it on the editmanager afterwards, cursor blinks fine, but then of course the document is editable which i don't want.

From your description, I don't know why its not blinking. If you can abstract it into a small application, I can take a look at it. The important thing is the blinkRate in the SelectionFormat. For non-editable text, since it won't get focused, this will be the unfocussedSelectionFormat that is critical.
