Open a folder

["maxdieci" <webforumsuser@xxxxxxxxxxxxxx>]

Hi!
 I've got a problem with Director 11 on Windows.

 With the former version, Director MX 2004, I could open a folder typing

 on mouseUp me
      open "[i]name of the folder[/i]" with "explorer.exe"
 end

 Now, if do the same, appears an error, saying

 "Director player error
 Use of unsupported Lingo command
 #open"

 How can I fix it?

 Thanks a lot, Max.
