The dissolve tool is not working for me when I use ArcGIS 10. It works perfectly when I use version 9.3. Any help?
I have found that not all tools work when your geoprocessing environment is set to run in the background. I believe that Dissolve may be one of these. Change you GP environment to Disable Background Processing and then give it a try.
I have not tested this but may be worth a tryTweet
