When I try to start Anarki via arc.cmd on Windows 10, the command prompt opens, but only the blinking cursor is visible and it waits endlessly. Only when I press some key (e.g. space), the text "initializing arc... (may take a minute)" appears. After about 30 seconds the arc prompt appears. But then, if I type something in that prompt (say, number 1) nothing happens, as if repl doesn't work at all. This was tested on Racket version 8.7. Please help!
