i haven't tried this with this hack, but i know it to be true of hacks in the past. hitting insert and arrow keys at the beginning and before the end of a match is alot less of a hassle than restarting every match.
the menu will automatically pop up if it's injected properly. try using topblast's Red Dragon Injector to inject. i haven't checked today but still worked last night so i'm guessing it's not patched yet.
