OK cool, that works...thanks!

Last question...how do i get the "All Readable Documents" to show up if
i'm using the 'popupExtension' method? i only get "All Documents," and
only after i specify the 'kNavAllFilesInPopup' flag in the dialogOptions.

do you only get the "All Readable Documents" if you use a TypeList
handle? (i'm not using one...)
