I just loaded a demo version (latest) on my desktop PC under Windows 95 and it runs like a champ. However, when I loaded it on my IBM Thinkpad, I get a "Stack Fault at eip=0002b502" error. Other addresses follow the one I just listed. The config.sys contains the FILES=30 setting.I have 4 mb of RAM on the Thinkpad. Any ideas? A sincere thanks to anyone who can help me. Chuck Bell
