Installation

4. Copy MiddleButtonJH.dll and MiddleButtonJH.ft into the CHOOKS folder.
5. Start Mastercam.
The same files can be installed separately in the CHOOKS folder of each Mastercam version from 2021 through 2027.
Opening the Settings Window

1. Open Mastercam's Customize interface.
2. Find the "Middle button JH" category.

Important Notes
---------------
- Compatibility has been tested with Mastercam 2021-2027.
- Do not install this build together with an older .NET test version. Duplicate installations may process mouse input more than once.
- Some Windows security shortcuts are handled directly by the operating system and may not be intercepted.
- If multiple Mastercam versions are installed, copy the DLL and FT file into each version's own CHOOKS folder.

搞定！
1. 请将 **`MiddleButtonJH.dll`** 和 **`MiddleButtonJH.ft`** 完全删除后重新安装。
2. 请在 **Mastercam 2024 的整个安装目录** 中搜索，确认是否存在重复的 **`MiddleButtonJH.dll`** 或 **`MiddleButtonJH.ft`** 文件。
3. 如果还残留旧版本的 **`Mastercam2023MouseControl.dll`** 或 **`Mastercam2023MouseControl.ft`**，请将其删除。
4. 请确认 **Mastercam 当前实际使用的 DLL 文件的 SHA-256 哈希值**，并把结果发给我。
5. 请确认并告诉我 **Mastercam 2024 的准确版本号（Build / Update 版本）**。
