ArcCatalog/ArcMap Shuts down when running script based tool

Discussion created by gbushek on Jun 16, 2011
We just upgraded to ArcGIS 10 and i've had trouble running my geoprocessing services. To troubleshoot the issue I added a new toolbox and a very basic script to that toolbox that does nothing but spits out a message.  I published the toolbox to the GIS Server and then added that service as a toolbox. Now when trying to run the basic tool, it completes with the message but then ArcCatalog shuts down. This happens every time no matter what script I use. I tried upgrading to SP1 but that didn't make a difference. We did not have this problem in 9.3. Ideas?
