I realize this is half a year after you posted your question, but I just started using V41 under Windows XP, 32-bit, and I don't have the problem you describe. I started in Large mode, set the calculator to ENG 5, changed to Medium mode, closed the program, and restarted it. Both digits of the exponent show up fine.
