There is a method you can use in ACT!, but it is rather tedious. You can also use an add-product called Advanced Lookup by Groups. It has a preset lookup for "groupless" contacts. You can download a 21-day full function free trial to try it out. I tested it and it works as expected.
Note: Effective 6/1/13, Sage no longers provides support for the Act! software. This is now provided by Swiftpage.
