on my system it runs fine. and i get the same errors so i suppose they are not related: (process:12833): Gdk-CRITICAL **: 08:33:23.453: gdk_screen_get_root_window: assertion 'GDK_IS_SCREEN (screen)' failed (process:12833): Gdk-CRITICAL **: 08:33:23.453: gdk_window_get_display: assertion 'GDK_IS_WINDOW (window)' failed (process:12833): Gdk-CRITICAL **: 08:33:23.453: gdk_cursor_new_from_pixbuf: assertion 'GDK_IS_DISPLAY (display)' failed i also just checked the code of NumericTextCtrl (https://doxy.audacityteam.org/class_numeric_text_ctrl.html#ab1f3c15d99790a22946c451036eabff1) and there is only one loop that imo in theory could run endlessly, and that's on line 334. but to be sure, you'd have to debug the code.
The behavior is the same on 3.3.3.
