Have you recently run TweakUI?  Did you uncheck the Search Results box on
the
Desktop tab?  If so that could well be your problem.

Using TweakUI make certain that "Search Results" is checked on the Desktop
tab.  If you haven't got TweakUI the latest version (1.33) can be
downloaded
from Microsoft and installed as follows:

If you don't have TweakUI the latest version of  TweakUI for Win Me (1.33)
can
be obtained from
http://www.microsoft.com/ntworkstation/downloads/powertoys/networking/nttweakui.asp

Download to a folder with a short name (e.g. C:\Tweak), run to extract
components, right click on tweakui.inf and then install, close the help
window that comes up to allow install to finish.  C:\Tweak can now be
deleted and TweakUI accessed via the Control Panel.

Just a few words of caution though if you are new to using TweakUI on Win
Me.
a) Do not change the first icon (My Computer) on the Desktop tab.
Doing this causes a number of script errors in Special Folders when using
either WebView or Active desktop.
b) Do not uncheck "Search Results" on the Desktop tab.
Doing this disables the Search in Explorer.
c) Do not hide the TweakUI icon on the Control Panel tab.
d) Do not uncheck "Show Control Panel on Start Menu" on the IE tab.
Doing this will prevent you from accessing the Control Panel including
TweakUI.
e) Do not uncheck "Shell Enhancements" on the IE tab.
This causes quite a few unexpected "problems".

See MS KB 274847 "No Search Results Are Returned After You Disable Search
Results" (http://support.microsoft.com/?kbid=274847).
