Seems like it's almost a year [but it's really less] when I purchased the previous version of ZT—at an Apple store...and I couldn't get it to work on my G5. OK, no problemo! Until the Apple store guys did a "sorry Charlie, contact the mfg." thing. Great, then it got worse from the website's non-answer responses and calling them made me sick & got me nowhere as to removing that "hiding" invisable backslash. No "techie" help came through to solve this little problem nor did I get any human email response. Gee, I paid full price & have given up trying to make a go of this fascinating game—months ago. I only hope nobody has the same nightmares I had trying to make this game-program function...and that their online & human tech support can at least do their job—like with some "after–sales service"? Who knows, this commentator just might buy another "game" from this company? Then again, that all depends if this purchaser can get the previous version to at least run. And to think I paid "retail" at an Apple store. Ditto.
