Before using Xbench 0.85b, there's two essentials points on which I would like to draw your attention:
1. Please don't extract the .lha with winzip/winrar on windows. Extract it only with the lha command on AmigaOS or the installer will crash with a guru.
2. In the installer, be sure to finish the path with a colon or a slash or it will freeze before the end of the installation.
Have fun !
