Little squares on my pages.

I think these little squares mean there is an error somewhere in transferring/processing the image. The maps also have a BIG square and a little red X. I tried uninstalling it and then after rebooting, I downloaded your latest version and installed it. (It was only a version behind, I think.) Same problem… I have a 1.7 PIV, 512 RAM, All-In-Wonder 32, XP Pro machine, with HD space to spare. All my other programs, IE6, Yahoo Email (HTML, too!) seem to show pictures and icons fine. HELP in Ohio. Are there hidden files I need to delete before another reinstall? [?]
