Command M measurement


Hi. I just updated to ImageJ 2.0.0 on macOS High Sierra using Fiji. When using the shortcut command + M to measure the results showed duplicated measurements. This does not happen if I click on the function under the Analyze tab.




Good day Gonzalo,

this is most likely a Java problem under macOS “High Sierra”.

For plain ImageJ see here:





I was able to reproduce your issue … I am running ImageJ 2.0.0-rc-62/1.51s / Java 1.8.0_66 (64-bit) myself on a OS X Yosemite 10.10.5.

The issue seems to be at least only the first time ‘command+M’ is used… afterwards, I get single measurements. Also - this does not occur when I use the ‘M’ shortcut alone - then it is also single measurements.

Thank you for pointing out this bug. I posted an issue on github.

You are right. I restarted ImageJ and the bug didn’t happen again.



Actually, with the new Java Update I am seeing all keyboard commands duplicated twice.
(measure, duplicate, close window).


This bug is fixed in ImageJ 2.0.0-rc-64, available now from the ImageJ Updater. See imagej/imagej-legacy@bab66b8d for technical details.
