All versions of ARGO have worked on my 133 and 166 mhz desktop computers with just the odd crash over the past couple of years but my laptop 166 mhz pentium Compaq  does not, and with the new version 131 is even worse. There must be something peculiar with the laptop. I am using windows 95/c but I notice Compaq alter 95 and use additional files unlike the standard desktop operating system.
