Hi Martin
Thank you for the feedback.
I have logged a call for the issue.
Also I have retested the transactions RSA1, RSPC and PFCG with the Blue Crystal Theme on our BW 7.4 SP8 system again and surprisingly it is working now. As far as I can work out, the only change I was doing was switching between the 2 themes (Blue Crystal and SAP Signature) in the SAP GUI 740 as part of our testing.
Regards
Derek
