Weird file permissions in Windows XP?

I’m running Office 97 (yeah i know i need to upgrade) on my Windows XP Pro machine. I just went out and bought a new machine to replace my Windows 95 machine. I installed Office 97 on my Windows XP machine to open a couple documents I created on my Windows 95 machine. When I open them on my Windows XP machine I get an error that says: “C:\…\ template.doc is being used by dave. Do you want to make a copy?” Any ideas on how to fix this?

Thanks.
