15C calculator BUG – HP 15C Calculator Review

As great as the original except fast. Minor thing. Appears to be a bug: after I run a programmed routine the X register blinks forever. Any key terminates the blinking. Q: why does the end of a routine always leaves the X reg blinking? A single function routine or normal 20 step routine ends with blinking X. Don’t know why. Previous v did not.
