I'm working with data from NHGIS, which is a great source for census data that readily joins to provided shapefiles based on the desired geography. I've been having increasing trouble lately when joining a table of census data to a shapefile, as almost everytime I do it, the join window goes into a 'Not Responding' state within seconds that it may or may not break out of. We had 10.2 and I just upgraded to 10.3.1 yesterday and the join performance is pretty much identical. This is on a Dell desktop with Windows 7 Professional and suitable specs to support this software.
Is there something I can do to address this? We need to do a lot of joining at work and I've got to make this happen quicker and more reliably than it is. Thanks for your help.
