| Loop ran out of time from drawing |

I've been making a program, and for some reason it crashes if I have draw too much stuff. I've tested it, and if I draw one less thing, it doesn't crash. When I started using ENet and Allegro together, they didn't work because of timing so I asked why on here I think and someone said to change it to that. Someone also said something about multithreading or something when I asked about it. How would I add that to my program? I need the ENet timing thing and Allegro timing in different threads. How could I do this? I can't really find anything on google. Should I use multithreading or something else? Here is the code for the server. 1#define WIN32_LEAN_AND_MEAN
