I’m getting a little confused now. For example, you made a function (capScreen) which you don’t use. Could you specify your could a little more so I can fully understand the structure and such.
Thanks for helping, btw!
can’t believe we spend so many posts on fixing this little problem. 
anyways, capScreen() just sets the bool to true and indicates that a screenshot should be taken. this value is then set to false if that happend. so you call capScreen() whenever you want a screenshot. really man, there is something wrong in your code. if you post more of your code it would be easier to imagine. did you at least checked the function link i posted?
