OTA upload doesn't stop

Arduino 2.01, latest Version
Windows 10
ESP8266 Adafruit Huzzah Breakout
#include <ArduinoOTA.h>

Same issue as reported by alezan
but The Output view freezes at "Uploading........................" and the status window shows "uploading" forever. I have to restart IDE to reset the state.
All works fine with Arduino 1.8
