Here is the code. All 869 lines of it. :-)                        
I would have snipped it and included only the relevant sections but 
i am totally at a loss as to why this is happening and hence dont     
know what the relevant sections are. Also included is the menu.h    
file which contains the #define 's and some XPM data.

Thanks again.
