Hi,
My colleague can’t open a fresh installation of DrRacket. She installed the DrRacket 8.5 Apple Silicon 64-bit version. Her screen recording <https://drive.google.com/file/d/1w5jvtq7QK5iAcVAjZA3VRw9z8a9H_fnz/view?usp=sharing> shows more details: - After trying to open DrRacket (00:00 of the video), no window shows up - Besides, DrRacket cannot be found in the Activity Monitor (00:08), which confirms that DrRacket is not running. - After trying to open DrRacket again (00:15), still, no window shows up - If you look at the Dock (the sequence of App icons at the bottom of the screen) carefully, you will notice that something shows up and then disappears immediately every time (00:02 and 00:16) DrRacket is opened. This suggests that DrRacket is closed immediately after being opened. Thanks, Kuang-Chen -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
