Strange bug in HP prime Virtual

[jte]

I was wondering how this thread would evolve…

My first impression is that “simplify” here might not be a “command”. It would seem useful (/ not too strange) to have simplifications not affect operations (beyond simplifying their expression). Unfortunately, “simplify(…)” is showing up on the left, looking like a command… (One might press Enter Enter Enter… think — oh, that could be simplified — press simplify, and resume pressing Enter Enter Enter…)

… and, moreover, selecting prior history items and tapping simplify does indeed affect operations (as the entry brought down, simplified, is what will be taken for Ans if Enter is used to repeat a command — unlike if a history element is copied as Enter will then copy the copied element).

Perhaps some UI adjustment is warranted here… (to clarify simplification actions, perhaps even to emphasize when, and how, Ans is playing a role).
