Shinedevil 8 Junior Poster in Training

I don't know where you sould put resources on this website so i'll just post it here. Also, if anyone can find the reason this program crashes occasionally and reply back, i'd be greatful! Thanks in advance.
*Reminder: I'm not pro

This is a simple(?) program that allows the user to change the resolution of the program to 5 preset options.

I know that there are some includes that are not needed and some code that serves no purpose, (was either trying to fix a problem, or trying to cover my program's ass)

*uses the allegro 4.1.1.1 game programming library
*This post includes all files needed for the program to work
*if anyone has a problem with this post contact a mod and they will deal with it
*all files are contained in a zip
*remember to actually have allegro installed if you want to use the code within the program
