I read somewhere and have encountered for myself that mouseExited
sometimes do not get called if the mouse moves too fast. Is there a way
to fix it?

To reiterate, the problem is that the mouseExited signal is not always
getting delivered to a component when the mouse cursor exits the
component. This is most apparent when the mouse is moved fast, but it
also does occur at slow speeds.

So the code shown on that thread does not work for you,
'here', and now?

The reasons I ask are that ..
- that thread was posted 5 years ago, about a particular
version of the Blackdown JRE for Linux.
- The code shown there works fine for me using AppletViewer.

I could investigate further with a variety of browsers and JVMs,
but am not in a mood to do so until I hear more explicitly from you.
Does that code fail for you? What Browser/Java Version are you using?

Hi Andrew,

Thanks for the kind gesture. I am unable to produce a scaled down
version based on my application to demonstrate the problem since there
are several mouse and mousemotion listeners involved. I will repost if
the problem persists.
