MinimWatch won't accept commands [Mac]

[simoncn]

Does this still happen after powering the Mac off and on?

What colour is the menu bar icon (red, grey, grey+red, transparent, blue, white or yellow)?

What options do you see in the menu (either greyed out or not greyed out)?

Do you have the early access version of JDK 9 installed on the Mac?

Please check the minimwatch.log file in ~/Library/MinimWatch. Are there any error messages there?
