Hi Nate,

Thanks for getting back to me. I didn't realise you did not have a set up at your disposal. Here is the run of gdb intro you requested. Please let me know if there is any thing else I can do to check this out.
I'm sorry if the tone of my last missive sounded grumpy, its because I feel a bit grumpy!
After this run of intro under gdb finished the partially constructed GUI stayed up. This is different from my other runs in gdb so perhaps all my down loading and compiling have changed  something.
If you can think of any test I can do to  help in this  please let me know.
