Can we use IBM iAccess for Windows V7R1 with an iSeries with V5R4?

List, Happy New Year to all!

Ok, I am having issues with my current IBM iAccess for Windows V5R4. My iAccess for Windows has also SI37892, as stated on:
http://www-03.ibm.com/systems/power/software/i/access/windows_sp.html

everything works OK but my only problem is that I cannot drag and drop documents normally. I always get the xxxxxx.tmp file that comes out of the process. Besides the software for V5R4, I also have the DVD for the IBM iAccess for Windows V7R1. I am looking forward to resolve the drag-n-drop issue and I thought that maybe I can upgrade my client program to V7R1. Is this a doable thing? Am I dreaming?

My laptop is a LENOVO ThinkPad T430 with Windows 7 / 64-Bit Operating System

Please advise,

TIA!
Peter Vidal
