If you open an application and place it above the dock (once you are able to see the reflection) then use your hot key for expose (makes all your windows fit on screen and you can choose which on to use) and once the expose takes over choose the application to make the expose disapear. You should still see the relection but if you do this one more time and this time click on the desktop (finder) instead of the app the reflection will BE GONE!!!
Apple should fix this small GUI bug.
