After running a simulation in LTspcie I tried to measure the current thought some resistors, but the ammeter did not appear as the cursor hovered over the parts. "Ok, no problem" I thought, and reinstalled LTspice. Voilà! The ammeter was back. I shut down the computer.

Upon restarting the computer and running a simulation the ammeter failed to appear. Is there a secret setting that I have been missing all these years?

 

hi Dick,
I have never observed that problem.
Could you post your 'asc' file and I will see if I can duplicate the problem.

EDIT:
Try holding down the ALT key, while clicking on the component or wire.

 

There is the file. The ammeter appears when I run it on the Mac OS but not on XP.

Holding down the ALT key did not help.

FWIW I've occasionally experienced the described difficulty while running LtSpice under XP Pro but not on Win7 Ultimate -- On a possibly related note, I have been unable to stipulate ammeter 'polarity' following installation of LtSpice upates Ca. 1 year ago...

Cursor becomes ammeter/thermometer icon ok here with your .asc file. Win10, latest LTS.

 

Same here, works OK.
Using Win XP Pro.
Latest LTS.

 

This is embarrassing as well as dumb. I introduced the problem when trying to get the program to stop leaving all of the intermediate files. I had unchecked "Save Device Currents" in the Save Options tab of the Control Panel. I was sure there was some switch, but didn't recognize it until all of you reported no problem.

Yes, I found the correct place to delete the intermediate files too.

Thank you for your feedback and help.

I dunno - It has been my experience that the described difficulty (along with several other 'simulation time' annoyances) occur randomly under XP (as of installation of an LtSpice update last autumn) Note that I have never encountered said difficulty under Win7 --- FWIW I put it down to the commonplace (if indolent) practice by developers of ignoring 'orphaned' OSes despite continued widespread use of same

Well hey! Pleased it's working for you!
