I've read one of the other forum posts indicating that the Find and Directions tools finally work for some users, however mine use to work on build 1200 and now when i click either of those buttons, ArcGIS Explorer crashes on build 1500. Here are my system specs:
Windows XP Profession Additionon, Service Pack 2 (32 bit)
Microsoft .NET Framework 3.5 Service Pack 1
Microsoft XML Core Services (MSXML) 4.0 Service Pack 2
Microsoft Internet Explorer Version 7.0
2.49 GHz - CPU Speed
Intel Core Duo Processor
3.50 GB of RAM
We have recommended ArcGIS Explorer to a client and in build 1200 they had issues of the Find and Directions tool not working. Even working with ESRI tech support, we were unable to resolve this. I don't want to recommend that they upgrade until i know build 1500 is stable.
