Inserting Datasource In Transformer Does Not Works When Using Citrix

[suheylkarakas]

For our users on a remote location we use Citrix to launch Cognos Transformer 10.2.1
When we try to insert a datasource from a report it logs on in Cognos Connection, shows the folders when I browse, but not the reports.
When I start Cognos Transformer on my local machine and open the same model, the report s are shown.
I use the same credentials to open the sources. I know for fact it's not an security thing in Cognos, while I'm admin and it works when I open it on my local machine.
I also logged on on the Citrix server itself. Started Transformer there, then it also worked. So it's not a server issue either (I think).
It only doesn't work when we start Transformer using Citrix.

Anybody familiar with this?
