How does "dcl_SelectFiles" function work?

The Function Document says
(dcl_SelectFiles {FileTypes [as List of Strings]} {Title [as String]} {DefaultDirectory [as String]})

I coded like this.
(dcl_SelectFiles (list "dwg" "dxf") "Open Files" "C:\Temp")

The dialog does not have "Open Files" title, the "C:\Temp" DefaultDirectory and the File Types.
Something wrong in my code?

This is now fixed in Alpha 5.

Thanks, owenwengerd.
I'm sorry I don't know what is Alpha 5.
5 means version of ODCL?
I've changed from 5.1.1.8 to 6.0.0.4 msi.
But both don't work as I coded.

Alpha 5 = Build 6.0.0.5
He means he fixed the code, but hasn't published the build yet.
He usually publishes on Sunday.

Thanks for information,   :)
