system beeps on keywords after uninstall

I uninstalled SQL Prompt while it was running and it stayed in the system tray. I killed the process and verified that no files were left on my system. However, even after a reboot, when I type a sql keyword, my system beeps as if it's trying to bring up SQL Prompt. Is there some registered key capture component that might be still registered on my system somewhere? If so, how do i remove it? Thanks.
