Actually, my machine is a custom-made 64-bit machine that is about three years old.  I had it when most folks didn't have a 64-bitter.  Irony is that nobody until the past year made a 64-bit graphics program that I could afford.  Now we have Poser 7 Pro something or other, but I won't buy it because I'd have to use Vista and although some folks have had little problem with Vista, I know so many more  who have.   I hope what you say about Windows 7 is true.   I just hate these suites of programs that we have today.  For example, you used to be able to get WordPerfect or Word by itself.  Now, you can't get except if you take on about ten other memory guzzling programs that you'll never need.  Same with all the security programs we have to have.  They not only cost us money, they cost us time, and they often use up most of our RAM.  Sometimes, I wonder if the virus wouldn't be the lesser of the two evils.
