show desktop not working

Running win98 2e. The “show desktop” icon in quick launch bar is not working. I have placed the proper .scf file in the proper place which seems to be the normal answer to this problem, but that does nothing. It appear that the .scf file is associated with no program to open it.

I have tried associating it with WScript and explorer with no success. I have downloaded new versions of WScript and JScript and have checked to see that scripting is enabled.

I used this constantly until it quit working and would love to have it back. BTW, windows key+d or windows key+m both work to minimize everything. Any help appreciated.
