1.14.1: Firefox 115.11.0esr (64-Bit) on Windows 7 freezes on start with BlockInterferenceControl enabled

[bastik-1001]

Describe what you noticed and did

With Sandboxie Plus 1.14.0, the configuration worked, with Sandboxie Plus 1.14.1, the same configuration does no longer work the same way.

My Firefox has passwords stored that are protected with a master password. Upon launch, the browser asks for the password. With 1.14.0 the window of the prompt appears, with 1.14.1 the window of the prompt does not appear, when BlockInterferenceControl is set to yes. I am not sure if that triggers it, but I wanted to mention it.

1) Have Firefox installed 2) Have BlockInterferenceControl=y 3) With 1.14.1 the browser window does not react to any input and I have to kill the processes

In 1.14.1, the only change we made to this feature is that the sandboxed process can not override the taskbar itself, so we can try adding an option to disable this part of the feature, then test again.

If that affects lots of people, that seems to be worth it. Otherwise, it might be the case that certain things just break and can't be used with everything.

[bastik-1001]

Confirmed to be fixed on my end.
