It is enabled and I cannot see the icons.

However I have found an error message in jminim-crash log file which starts

It looks as though the XToolkit class is not being found. I am using the following java which is the standard one for jessie:

java version "1.8.0_65"
Java™ SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot™ Client VM (build 25.65-b01, mixed mode)

I hope that helps

Thanks
