Well, might as well keep this thread going.
I would like to point out that I own a Microsoft mouse, and I have no problems whatsoever with Deck Editor. Although that doesn't confirm the previous theory, it certainly supports it. I'm not overly techy, but there you go.
Also, I have determined how to edit the decks used in Shandalar. Sadly, I have no place to post these edited decks (as I'm not the type to maintain webspace), so if anybody wanted a copy of the "Extra-hard" version, where the computer plays real decks, and not Oasises and Mishra's War Machine, and you have a small amount of webspace to donate to the cause, I'll be more than happy to send you a copy via e-mail (The whole thing would take up no more than 220k)
I can get more into that theorum if people so desire, but maybe I'm the only crazy person who wants to run the ultra-hard version...
