Sometimes need to select menu item twice

[rvalitov]

Hi!
On Alpine Linux when selecting menu sections sometimes I need to select them twice, i.e. it ignores my first input, screen reloads but stays on the same screen...

Hi @rvalitov — this should be fixed now in e64adab.

Root cause: press_any_key uses read -rsn1 which reads exactly 1 byte. When you press a multi-byte key (arrow keys, function keys, etc.), it sends an escape sequence like \033[A (3 bytes). Only \033 was consumed — the leftover [A stayed in stdin and got picked up by the next menu prompt, matching no valid option and causing the screen to silently redraw.

Fix: We now drain any leftover bytes from stdin after every read -rsn1, and also defensively at the start of read_choice before accepting input.

Run mtproxymax update to pick this up (along with the #37 broken pipe fix and the v3.3.32 engine upgrade).

Thank you, this is fixed now!
