Jay,
An OKL is an intercommand interrupt, that is it will interrupt running code between commands. OKLs do not wait for a user input wait state like other methods of key capture do. They were initially intended to be used for exactly what you are trying to prevent, to interrupt running code so a user could break out of a running process. That's why I suggested changing your OKLs to using menu short cuts intead becasue menu short cuts are NOT interrupts adn they will never interrupt running code as an OKL will.
I am not clear on why your efforts to undo the OKLs are failing but because of the nature of them I have found them to be interesting ( as is the chinese curse). They seem to sometimes defy logic and thus the reaon I avoid tham at all costs unless I have no choice because I need an interrupt in place.
