One of the best, but overlooked, new features in RDPclient is that in full-window mode the session's window can now be configured not to pop to the top of the RISC OS stack when clicked inside.
I often work on my Windows laptop in full-window mode (to allow multitasking with RISC OS) with various RISC OS windows in front of it and it's so much more a pleasure to use now that I don't lose sight of all my RISC OS work every time I use Windows!
