The problem has been resolved.

The previously reported problem affecting some applications running remotely on a Winflector Server with Windows 11 after installing the KB5124008 update has been fixed.

The problem caused context menus opened with the right mouse button to become unresponsive or behave incorrectly. In some cases, it could also cause the application to terminate.

We have prepared fixes for the following Winflector Server versions:

• 4.0.4.0
• 4.0.4.1

The fixes and detailed installation instructions are available here:

If you are using one of the above Winflector Server versions and experiencing the described problem, we recommend installing the appropriate fix.

It is no longer necessary to uninstall the Windows 11 KB5124008 update.
