Hero blocks my keystrokes... : Hero Online Discussions

Hey,

I've been hacking hero before, I use SCAR which is for RS basically clicks on colors and stuff. I used to send V and A keys for attack and heal my pet, also detect a GM question and handle it...
But I stopped playing for a while. So I downloaded and installed it again.
Next thing I know my keys sent arent working.. I quess hero has some protection for that... Can this be bypassed?

Any help is greatly appreciated.
Thanks,

Fort Ash
