autofilter problem

[Will Fleenor]

When working in Excel 2003, I apply a filter to my data by selecting my
range, selecting data, filter and auto filter. All the drop down arrows
appear. When I click on the drop down arrow, nothing happens. It will not
let me drop down to filter my search. This machine is running Excel 2003
SP2.

thanks, Will

One thought:
Inability to use autofilter is often connected to sheet protection. However,
normally you cannot apply autofilter if a sheet is protected. Might you have
a macro that protects the sheet between applying the autofilter and trying
to use it?
