problems with automation servers / win2000 client

I hope someone can help me: Client: Win2000, service-pack 4, Navision 2.01 I’ve problems with automation servers. For example: When I try to define a new Form for the table (Automation servers) then from that moment the navision application is hanging. I can only close Navision by killing the process. This error happens also under win2000 without service pack and also with sp1, sp2, sp3. Can anyone please give me the solution for that error ? Rolf
