This test java/awt/Mouse/MouseEnterExitTest3/MouseEnterExitTest3.html verifies that hw container doesn't receive mouse enter/exit events when mouse is moved between its lw and hw children.
When I drug mouse between LW and HW components the frame receives some of events (Exited and Entered events both) on Linux Suse 9.2 KDE
