Have searched for help with this, not found anything.

Occasionally after republishing, when I first view a page, it may have some misaligned text. It's easily corrected by hitting "refresh." However, I have some frequent visitors who experience this now & then, and seem oblivious to the "refresh" button, so I sometimes get notes telling me that something is screwed up in the design. I tell 'em what to do, that fixes it, no problem. I suspect some new stuff is bumping into some old cached stuff.

Is there a way to FORCE pages to refresh when viewed? I'm sure that would create slowdowns for folks who don't experience this. Any suggestions?
