I would advise you to make a copy of @PG_APL_OA_Binary103.pdl and to work with it with a new name.
Then open @PG_MotL_Standard.pdl and select the button csoBtnCommand.
Change Links\OpAreaPicture from @pg_apl_oa_binary103.pdl to that new_name.pdl.
And now study the Scripts of a Mouse Event, disable OK buttons, also maybe you should add a new Event (in a Configuration Dialog)..
I can't tell you more information cause I didn't try to do this task and haven't time for that.. :(
But I'm shure that I would have to do it, later.
