Sleep problems in AutoIt

I'm working on something, As the title of this section says, the Sleep function causes problems when the buttons are pressed, I have an If loop, with a random time between each mouse movement / click (this is an automatic program to automate the mouse click) However, when the sleep function enabled, I cannot click "Close" or "Stop" on the program interface,
