Sorry, my English is not good, the following content is translated software.
I am on windows 10 21H2, StartIsBack version 2.9.17. Because I am a China user, we need to use 2 input languages, i.e. English and Chinese Microsoft Pinyin. But when I use the win key to open the start menu and switch the input language, StartIsBack's start menu will close and I need to reopen it, it's a small problem but it affects the smoothness of operation, there is no such problem when I use windows10 official start menu. I hope it can be solved.
