RE: Think you know your HP-41?
he, he, ... peculiar little bugger indeed. Not a bug, since the phantom char is *not* really in the X-reg (only shown on the LCD) - so if you do X<>Y, X<>Y it's gone. But it's back there after pressing PRGM twice like the first time.

Playing around a little more we see it's the last ALPHA character "sticking" to the LCD, "K" from LBL "QUARK" but also happens with LCD flashing messages on startup. The only condition for it to happen is that X has the radix character, so this is a parsing error (but not a bug!). Remarkable, time to look at the source code....
