I'm a long time ZA user. When I "up"graded over the weekend from 8.4.02 to 9.0.114, my computer got veeerrryyy slow. Many minutes to open the task manager, or any program.
Running XP Pro SP2 on a Core 2 E6600 Duo desktop, with 4 GB of RAM.
I have 2 lines in my boot.ini file, one with the /3GB switch and one without. When I book using the one with the /3GB switch, I get this behavior. When I boot without that switch, no problem. Every time.
So, its pretty clear to me that the new ZA can't live with the /3GB switch while the previous versions have had no problems.
