This function is neither multi-thread or multi-task capable or safe.

Because of system restrictions on item ownership and using items, you should call this function from the task or thread which called InitControlPad().

InitControlPad() and InitEventUtility() create message ports and message items which only the task which has created them can use. Hence, DoControlPad() can only be called by that same task. If other tasks or threads attempt this errors result because those tasks or threads do not own the appropriate message ports and messages.

To make this function multi-thread capable, you would need to spawn a thread that communicates directly with the event broker, and with all the other tasks that will consume event information.
