Can't save Lotus123 files

Hi.

After we have installed Notes 8.5 on a Citrix server, we can’t save our lotus123 files.

We can open them and see the context but then we save the dokument the file is reduced to 0 kb.

We get this error entry in the event log:

The application, D:\lotus\123\123w.exe, generated an application error The error occurred on 02/13/2009 @ 07:26:03.954 The exception generated was c0000005 at address 6017B38E (nnotes!OSIsClientMainThread)
