Problem with gnu screen

I'm fairly new to screen use.  I have found a problem in my setup I hope 
someone can address.

I have a socket with two windows..  Both are started in screenrc including 
my browser in the first window.

Iuse the web browser lynx.  At least once a day, often the first time, 
when I want to go to an url on the web screen dumps me from the window 
with lynx to the second window.  The first window has disappeared.

Has anyone any experience with something like this and a possible 
solution?

Thanks.
