I helped a friend to use uecide. Everything seemed okay until he arrived at home.
Something was wrong with "boards".
Selecting "Tools -> plug-in manager" did NOT do anything. No plug-in manager window popped up.
We used teamviewer to see if I could do something remotely but the same result: no plug-in window.
It just sprang back to "Tools"
We both run UECIDE on Mac.
My installation is OK. Aswell on Mac as on Ubuntu.
