The code neznani posted is supposed to work. I'd only replace that "on ^[color:red]1:OPEN:?:{[/color]" by "on ^[color:red]*:OPEN:?:{[/color]".
Other than that, you probably have another OPEN event or something. Try placing this event in the first remote file you have in your list, above any other OPEN event you may have.
You might want to check if the default access level is set as 1 too (alt+r, Options menu, Default level: 1).
