That first link is great for previewing AVIs externally, thanks! I don't think that second link is helpful, though. I followed the instrutions, but there is no option to click a "Change" button in Windows 98 like in the animated GIF there. I really don't think it's a file association problem. As I already explained, in Windows Explorer, I can click and play using WMP by default no problem. The problem is within LW, and I can no longer click and play, like I was able to do before.
