Hi Mowcius,
I think I found the error in your code
if(line > 2){
line = 2;
prognumber++;
[glow]}[/glow]
if(prognumber > 4){
prognumber = 5;
}
[glow]//}[/glow]
menu();
}
I moved the } bracket from the commented out section to the other highlighted section and now I doesn't lock up.
I think what was happening is that when you press 2 button simultaneously it would make the line number = 1 and the prognumber >4 so the if statement would allow it to go though..
What do you think
Ben
