Starting with Windows 11 22H2, Microsoft has made internal changes in msctf.dll. The TF_Notify function, also known as CtfImmNotify from imm32.dll, uses a new convention for its third argument. These changes are incompatible with current versions of ZoneAlarm Anti-Keylogger, resulting in crashes in our main process. This patch converts messages forwarded by ZoneAlarm Anti-Keylogger to the new convention. If we detect the product and an incompatible version of msctf.dll, then we hook TF_Notify and detect any message using the old convention, and convert it to the new convention.
