Disabling mouse-over highlighting of toolbar buttons (winapi)

Is t开发者_如何学Chere any way (well, I'm assuming there must be) to disable mouse-over highlighting for a toolbar in XP? I'm just making standard Win32 calls for my application's GUI, through Common Lisp. Alternatively is it possible to implement custom highlighting?

Many thanks, ChrisM

What you are describing is called hot-tracking and is performed for flat style toolbars. If you want to disable it then remove the TBSTYLE_FLAT style.
