Ah ha - If i am right you want a GUID, it's a normal windows call so in theory it should work, don't know if it would carry over to the Mac version though, and I also don't know if you can call it through the scripting interface, best wait for Michaels reply on this one .... sorry. Hopefully we have narrowed it down to something workable.

Sample GUID = {3F2504E0-4F89-11D3-9A0C-0305E82C3301} ... Braces are optional
