Hi Umberto,
Would you please consider adding a timeout to the addon manager update screen whereby if a user does not select option 1,2, or 3 within a reasonable timeframe (20-30 seconds?) the program selects 3 and closes the window?
For us networked guys we have to go into the PC running the left, center and right IG and either update or select 3 manually. Unless you have a KVM hardware connection between your server and each of the IG's manually getting out of fullscreen mode, entering the IG PC's manually and checking #3 is a royal pain.
Thanks for your consideration
