I don't know about you guys, but after i searched this forum for a while, i can conclude that list of apps/widgets causing hildon to slow the device is pretty random, and per-user.

Most of listed never caused any trouble to me, however I just can't determine what is causing this so I can tell it's hildon itself.

I upgraded to 2.2.138 version which partially fixed problems with answering calls, and it just worked well until I overclocked with 'ideal' preset (500-950MHz in my case).

Before that I had lv set (250-850MHz) and everything worked well.
I will try changing preset to lv again, just this time up to 950MHz.
