I am not quite sure what argument I am in the middle of here but simply to say, if it clarifies things, though it probably won't, I strongly suspect that some Beyond the Swords mods such as Star Trek will work in MS Seven, as it works for me perfectly, and some mods such as Planetfall, sadly my favourite MOD, simply won't. Not until Maniac, the creator of that mod, works up a fix. It had been suggested to me that my hardware is corrupt but frankly that won't do as an explanation; I can play a wide range of other games no problem. Planetfall, and perhaps some other Beyond the Sword mods, have problems IMHO, actually, in my fairly confident opinion, with Microsoft Seven. I do not blame the modders and I do not blame MS Seven; it is simply the way it is.
Live long and prosper.
