Custom Cursor Blocks RollOver and MouseClick Events for Other Buttons and MovieClips

I need to hide my mouse and have a bullseye movie clip as a custom cursor. The problem is, I also need to click on things, and the code that I found on forums to create a custom cursor blocks the mouse from clicking on anything.

Mouse.hide();
var cursor_mc = new crosshairs();
this.parent.addChild(cursor_mc);

		cursor_mc.startDrag(true);

Is there a way to do a custom cursor that acts the same way as the mouse usually does?
