I am using Lubuntu 12.04 LTS. When I click on a icon to launch a program, be it from the start menu or from the panel, the mouse cursor does not change to a spinning circle (or anything else) to indicate that a program is launching. For beginners this is a very annoying problem.
I have tried to change cursor theme with
lxappearance, using either DMZ black or white, and it does not solve the problem.
