Blinking Cursor Issue

Question

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?
