How control Dialogue boxes zooming/fading in and out?

With an Aero theme dialogue boxes, menus, and open program panels kinda zoom or fade into and out of sight when you open or close them.

Is there a way to have them just appear and disappear without the animation and without messing something else up?

Thanks all.

Yes, I turned that off first thing.

Control Panel / Performance Information and Tools / Adjust Visual effects

My recommendations are to uncheck:

• Animate windows when minimizing and maximizing
• Fade or slide menus into view
• Fade or slide ToolTips into view
• Fadeout menu items after clicking
• Slide open combo boxes
• Smooth-scroll list boxes
