I don't use Windows, so this may be different for you, but sometimes I've found that with Explorer, stylesheets are not cleared by doing anything except quitting the browser. I don't know if this will apply for you, it may not be related to the changes you're trying to make, but since no one's replied yet, I thought I'd pass this along. If you're using an external stylesheet, the one work-around I use when I can't see changes I've made is to load the changed stylesheet directly into the browser. What I mean is put the address of the external stylesheet into Explorer so you're opening the stylesheet for browsing. Once you've done that, you can reload your html page and you should see the changes made.
