Capture works, it can place a screen cap on the clipboard while being sandboxed,

EPSnap and Hypersnap create Hook alerts from Defense+ even when sandboxed, when I Block the Hook alert I can’t capture screenshots, do you have any other tips on how to reproduce?

Thank you very much for your response.
EPSnap and Hypersnap install the hook is just a keyboard hook or a mouse hook,
there’s other screen capture are still blocked when the hook installed,
so I think the hook and screenshots are not related.
Hope comodo going better!
