Black Screen

For some reason when I'm hacking I get a black screen that fades in. Can anyone help me out?

Give more of a detailed explanation of what you are doing.

is it when you change your size too big?

Not for me. Basically I enter a map turn godmode and ohk on as well as pally. Then it fades out black. most of the time its only when i turn on god and ohk that it does it.
