Microsoft Pinyin seem to be the culprit, if you turn on the compatibility option in Microsoft Pinyin (to use the older version of MS Pinyin) then the problem is gone. I installed WinDbg on his machine and peeked at the Thread 0 and got a backtrace like this:  Looks really similar to my previous discovery (Shift key freezing). This issue doesn't appear to happen on every machine though. I didn't have the time to ask him to install a newer build for testing... # Steps to reproduce <!-- If there are multiple steps to reproduce it or it is a visual issue, then providing a screen recording as an attachment to this report is recommended. --> <!-- If this issue is specific to a project, please attach the necessary files to this issue. --> 1. Make sure you're using Microsoft Pinyin and the compatibility switch is turned off 2. Launch KiCad, create a project and add some stuff (or just open an existing project) 3. Press M when the IME is at English state (you'd have "英" at the tray), freezes  # KiCad Version <!-- Copy version information (from main menu Help->About KiCad ->Copy Version Info) and paste it between the triple backticks below to preserve the formatting. --> ``` Application: KiCad PCB Editor (32-bit) Version: (6.0.0-rc1-267-gb35aa302e2), release build Libraries: wxWidgets 3.1.5 libcurl/7.78.0-DEV Schannel zlib/1.2.11 Platform: Windows 10 (build 17763), 64-bit edition, 64 bit, Little endian, wxMSW Build Info: Date: Dec 1 2021 00:14:16 wxWidgets: 3.1.5 (wchar_t,wx containers) Boost: 1.76.0 OCC: 7.5.0 Curl: 7.78.0-DEV ngspice: 35 Compiler: Visual C++ 1929 without C++ ABI Build settings: KICAD_USE_OCC=ON KICAD_SPICE=ON ```
