ZenWorks Policies

I am running ZenWorks 3.2 in a NetWare 5.1 environment with Windows 2000 workstations. One of the policies that I am trying to implement here is the “Run only allowed Windows applications” one. If I check that box and add some executables in the list, with or without the complete path, it does not work the right way. When I enable the policy, it blocks all applications, whether or not I have them in the list. I’ve tried searching on both Microsoft and Novell web sites, but did not find anything. Please help.
