Disable option LKASP_CALC_ON_CHANGE_ONLY
There is a problem: enabling/disabling/ack/etc will not show up until a zoom is performed.
So there is no more instant view of what is happening.
No need to use this option because there is no safe solution, and it is not worth trying due to the fact
there are no cpu benfits.
