It was working for me in 1.4.9 and SAP Gui 740
One thing I recommend checking - if it is not working for you - as I had a similar issue in the past (pre SAP Gui 74) is downloading a SAP Gui Patch - in the past on the Software Distribution Center I found a Gui patch for "Business Explorer" - could you check there? It has been a while so I am totally basing this answer on my memory.
