I just updated Photoshop CS6 Extended and now whenever I use the "Select Color Range" tool the dialog box does not open and Photoshop locks up. I can still click on menus but most everything is grayed out. When I click on any tool I get a system error ding. Same thing happens when I try to close the image and even Photoshop. I can not close Photoshop at all - by normal means. I have to use Windows Task Manager to kill Photoshop. I'm running Windows XP with SP3.
