When I launch the Arduino IDE app, the start-up image comes up, then the Arduino icon appears in the toolbar to the right, but when I click on it, nothing happens.
This problem just came up today. A few days ago, everything was working just fine.
I am running Windows 10.
I tried a computer re-start but got the same result.
I un-installed the IDE software and re-installed it but got the same result.
Has anyone run into this issue before?
