MinimServer Greyed out on QNAP 451

[simoncn]

Clicking on the MinimServer icon in the App Center (My Apps section) should open an information pop-up about MinimServer. It does this whatever the state of MinimServer (running or stopped).

If the icon is greyed out, the Open action should be replaced by a Start action. The Open action is only available when MinimServer is running (icon colour is green).

Do you see any messages related to MinimServer in the QTS system log after the problem happens?

I am not able to try the x64 version of MinimServer 0.8.4.1 because my QNAP is an ARM model, not Intel.

There is also a 0.8.4.2 x64 version available for download that might improve this behaviour. Please download it from this link and let me know if there is any difference.
