I was trying to merge tim's change with mine, so the image was definitely
not clean.
This involved many action, correcting SyntaxError, etc... breaking an
image, killing the process, and restarting all over again.
If I remember, I got such error first in a MC merge window.
I also remember some strange warning 'This modal dialog was interrupted,
please close it'... This could be from MCTool answer:
Generally, the red squeare is not solitary, they like to burst in flock, so
I suspect some ill state of the World, like having several UI processes?
But currently my image show no extra Process in the ProcessBrowser
