Must be quite a long time - maybe be more than eight years - I remember I discovered the game at a time I did not have a permanent internet connection - it was Win 3.11 then? - had to hunt for time to dnld scenarios!
I've just installed the 32bit version on a Vista PC and plan to have another go at The Gallows too just to keep the scent warm. No time catching up with the forum, though...
I still hope there might be a way - eventually - to be able to play them all once more...
