It was puzzling me why this was still happening for you both when my tests are running fine but think I’ve tracked it down now! The fix in 24.1.2 fixed it only when using the psychtoolbox backend - in ioHub there was an additional adjustment needed, I didn’t catch it because my tests happened to be using the last backend I tested with (which was psychtoolbox). Will get a .3 release out ASAP with this fully fixed! In the meantime, go to Experiment Settings → Input and set the keyboard backend to “Psychtoolbox” to avoid this bug.
