My lead is correct - it seems to be a win2k problem (just sent a game in win95 and it worked first time). I have the giveio.sys driver installed in win2k - sending to the v64jr works fine with it - but for some reason the swc doesn't want to know. I'll have a play with it later today and i'm sure it'll be fine (i seem to remember reading some posts further down the board about this - will go look now...)
Thanks for the help,
