I have a Panasonic Toughbook CF-50 circa 2002. It has a 1.5ghz pentium M single core and its maxxed out at 1.25GB RAM. Somebody on another forum mentioning this browser problem for XP. Had me scratching my head. So I got it out and fired it up. Yea, its really a tough old thing, refuses to die though I hadnt regularly used it in some years. Last I used it, think it was pretty much as ebook reader.
