I have Elementary OS Freya on my desktop computer. I installed some applications, which appear in toolbar (dropbox, steam, xneur, ...). But when I open an context menu from toolbar icon and select any item, then nothing happens. Sometimes it repeats with language indicator. What's wrong?
P.S. I think I found the cause of the problem. I tried to open the menu options via right-click. Left mouse button works successfully. Does anyone know how to fix it?
