Technical Information
---------------------

As you can see from the source code, this is a very small and simple
program. All it does is search for PointCast, search for the ad window,
and send it a SW_HIDE command, causing the ad window to vanish. Changing
panes will cause the window to be redisplayed, so the message is resent
every second. If PointCast exits and is restarted, the program will find
its window again.

If you run the program again while it is already running, it uses a mutex
to signal the running copy to exit. The running copy sends a SW_RESTORE
on the way out to bring the ad window back up.

Programmers: There is a better way to do this with message hooks. However,
that requires a separate DLL file, and is noticeably more complex. This is
a low-tech approach that works. The disadvantage is that you will see the
ad window pop up momentarily after changing panes.
