Thanks to all those who helped me out with XDrawLine.
I've managed to get real nifty looking lines on my screen, but there
is just one problem:

Whenever a window appears over the lines and disappears, or the
application is iconified, the lines (or portions of) disappear.
I suppose this is because the lines from XDrawLine are not
event driven (ie: no auto refresh).

For a solution, I attempted to figure out when an event such as
realizing a window or window movement occurs, but, unfortunately
I could not find/understand the required info from the Xt Intrinsic
or Xlib manuals.

Is this the best solution to this problem?  What is the proper way
to check for the required events, and how should I go about
keeping those cool looking lines on my screen?
Any help appreciated.
BTW, I'm using the Athena widgets (but that shouldn't matter, should it?)

Thanks.
