Hello, we have lots of rectified images in many separate folders and sub-folders. The layers in ArcMap-Arcview (desktop single use) linked to the images. When I use ArcGIS 10(recently switched from 9.3 to 10 ) without any service pack, I can turn on and off layers very fast. When I install service pack 3(or service pack 1), then it becomes extremely slow to turn some layers on and off. The only way I could solve the problem was to uninstall service pack. My computer is a fast computer(Dell T7500, Xeon X5680 3.33GHz, 12GB ram). Any idea what the problem is? Thank you very much for your help.
