### Before reporting a bug, please complete the sanity checks above.

- [x] I have done the sanity checks, and my issue persists.

Same version on both Server and Client

### Build types

Official release (installer/package from GitHub releases)

### Deskflow configuration

- Windows 11 Server and Windows 11 Client

### What steps will reproduce the problem?

Running this setup for few years already. Even few times already changed Server and Client hardware completely. After installing latest windows updates released Tuesday (6/9/2026) this week: can't use back/forward keys on my mouse (not sure this info is important but still - logi mx anywhere 3s) - just nothing happens

### Additional information

_No response_

No source file or test is named. Start by reproducing the failure on Windows 11 25H2 with Deskflow 1.26.0.236 after the June 9 updates, then trace the mouse back/forward input path and collect logs; done means those buttons work again between the Windows server and client.
