Effect: Perform any hooked actions needed when the user selects

currently logging, record the need to relog and CANCEL
the dialog, never letting the real dialog proc get the
OK. Remember, this is actually a file open dialog that
we have perverted. If we let the OK through, the common
dialog manager will try to open it and it will inform
the user that the file is locked. This way, we let the
user click OK, but the dialog thinks we cancelled.

Called By: LogOptionsHookProc only.

Returns: Whether the message was handled by this function or not.
