I am using Select By Attribute to find all NULL values of a particular layer. The field is joined from a CSV file. When I use the wizard, select the field, and choose "Get Unique Values", NULL shows up as a choice. So I double click the field, select the equals sign, and double click NULL, then press OK. ArcMap immediately ties up all resources and crashes about 10-15 secs later.

Any ideas?

ArcGIS/ArcMap 9.1

ArcGIS can be unstable when it comes to joins, especially with mismatching data types (ie geodatabase and csv table). Try converting both your shape data and your table data to geodatabase format. That usually works for me.

Thanks Paul, haven't had a chance to try it yet but I understand your point exactly, and I'm sure this will solve it. What a pain.. I can't wait for native Excel support.

I can't wait for ArcGIS to be as stable as Manifold. ;)

Native Excel support (and a lot of table handling improvements) are in ArcGIS 9.2, currently in Beta test. The release also has many fixes which should improve overall stability.
