Problem of File Browser.fp

[尤文蒂尼]

Dear all:

    I use File Brower.fp of cvi in my program, and find a problem. In the right box, when I select a dir and double click, it can't expand to

display its sub dirs and files. I only can expand by double click it in the left bos. It seems that the right only can display dirs and files, but

can't expand dirs and files.

    In the standard windows file browser, we can do that both in the left and right box. Can CVI realize this function like windows?

    Thanks a lot !
