Hi Andrei, can you try this: Open Pharo normal (no headless option). Change the window size to "not-maximized" (eve if it is actually not maximized, maximize it ones and change it back to "not-maximized") Save and quit the image. After that, a call like pharo --headless pharo.image eval "DateAndTime now" will write the output to the stdout file, without opening a window.
