Make sure the NUMLOCK key on your machine is "on". Run the DevStudio example, and in the BCGDev1 window, hold the key down and type "0128". This should cause the european currency symbol (euro) to appear in the window. If I go back to release 5.0 (the demo) this worked fine. Starting in release 5.1, with NUMLOCK on, a question mark appears. This is a very complicated bug, and I can't figure it out.
