Hell no, it was a first time. Usually vi stays in processes and load the cpu, but this is an only app I have this sort of problem with.

And I noticed that even if I change cpu frequency to powersave ASUI shows 400 mhz (red color) and advanced battary shows 165 mhz at the same time. I waited about a minute after I changed the frequency and nothing happened. When I close all applications (actually only quasar, but it was an only runing) it finally changed to 165 mhz.
I will try to repeat it next day to tell you more about it.

May be somebody can help u? I can ask Mitrandir, he has some experience (Layout switcher, Telescope launcher and telescope task switcher)...
