    I suggest you upload a simple example of the fault and tell us you did that.

    Thanks Tony for the suggestion. I went thru all the Settings screens and I set "save currents".

    Ltspice current probe direction

  • Ltspice current probe direction
  • Ltspice current source
  • Ammeter in ltspice
  • Ltspice power measurement
  • Current probe ltspice
  • But my system operates the same: when I hover cursor over the ends of a component I get a voltage probe which works fine when I click it. But hovering over the center of a component does nothing as it always has with the current LTSpice installation.

    Perhaps my mouse isn't working correctly but it has performed normally otherwise for me for a year or so. I'm stumped... Rob

    What kind of component did you hover over?

    It depends on whether it is:

    • A 2-terminal part like a resistor,
    • A 3 or more pin part like a transistor or IC,
    • Or a sub circuit model (custom part).

    Did you remember to save the settings, and then run the simulation again?

    Rob,

    Just to be clear about this:

    That LTspice setting affects whether or not the currents are saved in the .RAW output file whe
