There is no real overflow fix for cod 4 it will overflow maybe a little bit later but if you open this menu up allot through out the game it will still overflow just not as fast. All the overflow fixes do is give you more strings which is still very easy to go over then overflow.
For example:I have every overflow fix know to man for cod 4 even some that have never been released and my menu uses 3 setetexts (Not including the menu its self) and after i open it 15 to 20 times or use a doheart for about 2 mins it overflows. Intel someone finds way where we can select how many strings to have or find a unlimited string fix it will still always overflow.

i bet your using \n wrong

I dont think so cus i have a total of 300 and somthing strings. The reason why i have never finished and fixed my menu "The New V1" Is because i couldn't get it to stop overflowing idk though maybe some settext not deleting right.
