The buttons "z"/Undo-function messes with the treshold/colour picker function




my plan was to use the treshold function (black and white, dark background) and to select with the colour picker my region of intrest.

This worked absoloutly fine until I reinstalled ImageJ/Fiji. When I press now Ctrl + Z or even go in the menu Edit -> Undo (with the mouse) my image turns red/black.

I tried to reinstall the program. I also have this problem on diffrent computers.

Does anyone know why this happens?



Sorry that this has been sitting unanswered for so long. Are you still having this issue?

I wasn’t able to reproduce, but I am not sure about the exact steps you took when seeing this. Can you maybe post detailed instructions how to reproduce the issue, or record a simple macro?
