AS3 Apache Flex: click randomly not updating stage until mouse moves - actionscript-3

Question

I have a SWF that displays a field of stars as a single BITMAP added to the Stage. The image is dynamically generated through the Bitmap's BitmapData, to allow trackball interaction with the star field. Planets and other buttons are also on the stage with hint Labels underneath.
All works as expected. However, sometimes clicking a button, performs an operation, that does not show up until the mouse moves. For example, clicking the button to toggle planet labels, will immediately update the stage with labels turning on and off. But sometimes, the click does nothing, until the mouse is moved, or another click is made and then both clicks activate in series.
Same goes for a button that resets the star field to show either the Sun to Earth or Earth to Sun view. Click the image (button) and the background star field updates immediately. However, sometimes it does nothing until the mouse moves. It seems like an interface timing issue beyond my control.
Anybody encounter this situation? Working on MAC with Firefox, all latest updates.

Here's the event code.
private function moveRespond(e:MouseEvent):void {
var X:int=mouseX,Y:int=mouseY,R:int=Assets.Assets.radius/10; if(R<15){R=15}
if( moveActive ) {
Assets.Assets.STUFF.view.rotateMatrix(PT.x,PT.y,X,Y);
FIELD.update(w,h);
}
else {
Assets.Assets.STUFF.line.hover(X,Y,R);
var btn:Vector.<Button>=Assets.Assets.BTN_list;
var i:int,I:int=btn.length;
for( i=0; i<I; i++ ) {
btn[i].label.visible=btn[i].hover(X,Y);
} }
DP.x=PT.x-X; PT.x=X;
DP.y=PT.y-Y; PT.y=Y;
}
private function upRespond(e:MouseEvent):void { moveActive=false }
private function downRespond(e:MouseEvent):void { moveActive=true;
var X:int=mouseX,Y:int=mouseY;
PT.x=X; PT.y=Y;
}
private function clickRespond(e:MouseEvent):void {
...
//lots of button management, similar to above
//FIELD.update(w,h); and new zodiac sign fetch...
//but if there was a soft error in here,
//then the click at the end would get skipped,
//and it doesnt.
...
if( click ) { Assets.Assets.soundClick(X); }
}
Because of the randomness of the error, I'm assuming a memory thrashing somewhere in my code that is interrupting the next event, but kinda hoping its a communications issue because the missed-click is Event-queued. It just doesnt get sent to my App until either a move or another click. The App.swf can be run without the wrapper (preloader basically), and it has the same randomness. Even though it is very rare, it is still very annoying.
There is also a ConstantUpdate timer:
public function constantUpdate(evt:TimerEvent):void {
Mouse.hide(); Mouse.show();
dateMessage();
if( !Assets.Assets.BTN_help.glowing && Math.random()<0.05 ) { Assets.Assets.BTN_help.glow(); }
if( !Assets.Assets.BTN_logo.glowing && Math.random()<0.01 ) { Assets.Assets.BTN_logo.glow(); }
if( !Assets.Assets.BTN_next.glowing && Math.random()<0.05 ) { Assets.Assets.BTN_next.glow(); }
Assets.Assets.BTN_help.update();
Assets.Assets.BTN_logo.update();
Assets.Assets.BTN_next.update();
Assets.Assets.BTN_star.update();
Assets.Assets.BTN_note.update();
Assets.Assets.BTN_moon.update();
}
Just more button management. The Mouse hide/show pings the Mouse after the contextMenu deactivates. Otherwise, the mouse turned into an arrow over the contextMenu and would stay that way until mouse left the window and returned. Still have some mouse hick-ups on startup though - not setting my cursor after App.swf loaded. Have no idea if that is related to the clicking issue, but here's that code:
var cursor:MouseCursorData=new MouseCursorData();
cursor.hotSpot=new Point(
Assets.Assets.BTN_sun.icon.width/2,
Assets.Assets.BTN_sun.icon.height/2);
var pointer:Vector.<BitmapData>=new <BitmapData>[Assets.Assets.BTN_sun.icon.bitmapData];
cursor.data=pointer;
Mouse.registerCursor("myCursor",cursor);
Mouse.cursor="myCursor";
I dont keep a local handle to the cursor object.
