I've attached the cygcheckout.out file. python3.9.18 seems to work fine, but when I run ipython8.18.1 it hangs after tying any command. e.g. *---------~:1671> ipythonPython 3.9.18 (main, Dec 22 2023, 06:22:36)Type 'copyright', 'credits' or 'license' for more informationIPython 8.18.1 -- An enhanced Interactive Python.

I hope I'm sending this to the correct email address. I've been using Cygwin for years (since the late 90s), and I've never reported a bug before. The website is opaque. I'm sure you'all are trying to avoid spam, and perhaps I would have asked annoying questions if it wasn't. But I'd actually enjoy contributing. However, every time I consider it, it starts a bit steep. Whoever is making Cygwin happen is doing a great job; in almost 30 years, the tool has been much improved. Thanks! --------------------------- Emilio (eo) Rojas ---
