Folder Option Problem

Dear Techrepublic,
I have got a problem with folder option’s option.
When i’ve chosen the Show all files option and exit this window, there is no files appear.So i recheck my option again, at that time i saw that “Do not show hidden files” option is on .
So i change the option to “Show all hidden files” option to On and apply and exit.But same thing also happen next time.
So help me with this problem.
Thanks for your cooperation .
with regards,
