[Sheflug] awk-ward problem

Hi Guys,

I'm pretty dumb with awk but I know some simple 
one-liner should do what I want more elegantly
than the program I wrote to do it.  I just need 
to delete a recurring text block from a file.
The following:

awk '/Cannot connect/, /Graphics support/' testc.inp > testc.out

does exactly the opposite (ie keeps what I want to 
throw away and throws away what I want to keep.)
I've tried various things with != in there but 
I'm not getting it -- HELP!

Many thanks,  Jan
