Thanks guys. Turns out this was a memory management issue on the part of VISTA. Apparently not only does VISTA take up much more resource room than it should, It doesn't seem to release memory as it should after programs are closed. This is inexcusable, but not unpredictable. Want a good one ? Apparently -7 is supposed to be better- ALMOST as good as -XP was ! Did you catch that ? 2 O-S releases later and we're ALMOST as good as we used to be managing memory ! Ok the solution ? Why we should all go out and spend HUNDREDS on MORE MEMORY and an O-S that'll use it ! Of course, it'll be up to you to deal with either REPLACING your perfectly good software - at a a cost of THOUSANDS of $$$$ or just deal with the incompatibilities ! Cost of progress anyone ? Ok, this doesn't add to the conversation here, but it DOES go to the question of the practicability of constantly upgrading when it should only be necessary for the benefit of a business considering the expense.
