Screensaver with webbrowser control

[te.richardson]

I want to write a screensaver that plays powerpoint presentations.
So I have a form with a webbrowser control.
Is there any way to get the containing form to know when the user has
moved the mouse if the user moves the mouse over the webbrowser
control?

At the moment I have the webbrowser control only 90% of the full screen
size (the containing form is full screen size), and the screensaver
terminates when the mouse is moved into the screen area outside the
webbrowser control. So it works. But it is not satisfying.

This is my first c# program (first .net program in fact).

thanks for any help. I realise this is a non-trivial question;
Powerpoint 2000 itself doesn't seem to implement mousemouse events
during a slideshow, although I don't have much experience with
Powerpoint macros.
