Minimizing 188.8.131.52 window breaks the tool bar so that it requires going to the task manager to return to the application. This occurs if the application was not launched from a pinned icon in the tool bar. My tool bar was somewhat full but the up/down arrows did not appear. Otherwise the new version seems to be working fine. Easy work around to just pin the application icon in the tool bar and start from there. Laptop was running Windows 10.
