You can talk about issues with k-meleon here.
K-meleon using a lot of CPU in idle state

I wonder if this is suppose to be normal.
I don't use k-meleon much, but the other day, I wondered why my laptop was starting to overheat, when i thought it was really do nothing.
I had nothing open from a clean boot but k-meleon with a single wikipedia page displayed, then I decided to look at task manager.
k-meleon constantly jumping from 30, then 70, then 80, then 30, then 60, etc, never under 30.
This is from a clean install of Windows XP - SP3.
Maybe it was trying to play an animation somewhere, anywhere i can get a list of best optizimation settings, to turn off any eye candy?
