Hi,
Some addtional information for you.
1. I have pulled the machine out of security zone, uninstall, clean user profile temproary files, and reinstall the 64-bit version. The problem remains. (OS: Window 7 64-bit)
2. Uninstalled the 64-bit version, installed the 32-bit version, it works.
The problem appears with 64-bit version.
Hopefully, this points direction to debug.
Helen
