ik trouble

when i set up my leg or arm i notice a little bug or trouble. i use detach foot method . And i notice that the knee flip at some position. To correct this i need to activate the stretchiness of the ik solver. but as i m not a big fan of it(it scale in all direction) i will prefer to disable it.So is that a normal behavior?

to help control knees, have you tried this:
