Erasing old bullets in favor of new

[Alterego]

I'd like to have a menu such that you can choose alternate processor priorities, and having done so the one you just chose is bulleted and any others that may have been bulleted in the past no longer are. Here's the relevant code i'm trying. Basically it doesn't work and it bullets every item every time you select it

$options = GuiCtrlCreateMenu("Options",-1, 1)
$processor = GuiCtrlCreateMenu("Processor Priority",$options)
$priority1 = GuiCtrlCreateMenuItem("Below Normal (Suggested)",$processor,0,1)
$priority2 = GuiCtrlCreateMenuItem("Normal",$processor,1,1)
$priority3 = GuiCtrlCreateMenuItem("Above Normal",$processor,2,1)
$priority4 = GuiCtrlCreateMenuItem("High",$processor,4,1)

GuiSetState()
While 1
$msg = GUIGetMsg()
If $msg = $priority1 OR $priority2 OR $priority3 OR $priority4 Then 
       GUICtrlSetState($msg,$GUI_CHECKED)
       For $x = 1 to 4
           $y = StringSplit($priority1 & "," & $priority2 & "," & $priority3 & "," & $priority4,",")
           If $y <> $msg Then
             GUICtrlSetState($y[$x],$GUI_UNCHECKED) 
           EndIf
       Next    
   EndIf   
Wend

Seems like it should cycle through the four and make sure they aren't checked

this line is wrong:

If $msg = $priority1 OR $priority2 OR $priority3 OR $priority4 Then

should be:

If $msg = $priority1 OR $msg = $priority2 OR $msg = $priority3 OR $msg = $priority4 Then
