I just installed Roli Connect on Windows, and I couldn't get it to work at all. I was clicking on the tray icon, but nothing happened.
Turns out this was because instead of having the task bar on the bottom of the screen, I prefer to put it on the side of the screen.
So I did some tests, and the results are that Roli connect doesn't work when the taskbar is on the left or right side of the screen, but does work when it's on the bottom or top.
This is on Windows 10.
Thanks Francis, we'll look into fixing this in the next update.
