BetterTouchTool Not Working

MacOS: 10.14.6
BetterTouchTool: 3.202

I have a problem with BetterTouchTool. When it works, it's great; but it often doesn't work. I haven't quite figured out why. At first, I thought it was a sync problem, but reselecting the default profile didn't work, When BetterTouchTool is the foremost window, things work perfectly; but, when it's not, they don't. There's obviously something that I've missed in the configuration settings! I'm, of course, perfectly willing to provide any debug information if you tell me what to do :slightly_smiling_face: Thanks in advance, Alessandro
