Can't make changes to footers

This problem has resurfaced again. It's related to the "can't type and S" in headers and footers. I try to make changes to the text in a footer, but it won't take. My IT department used the fix that was originally provided by Ron. That fix was to replace the dhtmled.ocx and  triedit.dll. But it didn't work this time. Is there another fix that might work?

Thanks,

Rob
