Ugh, I can't take it anymore. I definitely prefer NX to ACR, but it's so sllllllooowww! My desktop is 2 years old, but I really can't justify buying a new one right now. I am using a Dell Dimension 3000, Pentium 4, 2.8 GHz, 768 MB RAM. I read somewhere that NX works faster with .NET 2.0 so I installed that and deleted 1.1 to be sure it was using 2.0. That seemed to speed it up a bit, but not enough. I had 512 MB RAM and then bought another 512 yesterday, but discovered that I had two 256 sticks in there so I am only up 768 MB. Would buying another GB make a difference? I keep getting the virtual memory is running low error message. I have removed spyware, defrag'd the hard drives (I have two 7O GB on it now because the laptop is out for service so its hard drive is hooked up to the desktop), run disk cleanup, etc. What else can I do before buying more RAM?
