empty folders

This occurs with several CVI versions (my latest is 2012). When using the function DirSelectPopup or FileSelectPopup and steering over to a folder that has numerous sub-folders or files, I often (not always) get an empty folder displayed. The only way to see the sub-folders or files is to back out one level and select that same folder again.It may take 2 or 3 tries before it works. It appears to timeout if there is too many sub-folders. Is there a solution to this annoying problem? I see it on Windows XP and 7.

Thanks, Mike
