SAP GUI 7.20 installation in Citrix environment

Dear colleagues,

does anybody, if there are some hints using the SAP GUI 7.20 in Citrix?

We've different installations of the SAP GUI; one installation szenario is local on the client workstations and one is on a citrix environment.

On the local installation, the SAP GUI 7.20 works fine so far, but in Citrix the menu looks strange.

Is it possible, that we need a different installation server because on the client we've Vista; on Citrix it's 2003 Server?

Thank your for any advice + best regards,

Clemens
