IK rigs not working properly

Ive been trying to get IK rigs right for as couple of days now and everything seems to be going wrong…everytime the mouse moves the bone always moves towards the same direction… any one know why

A Chainlength that’s too long (even if it’s zero the dotted line can run from the tip of the foot bone all the way up the spine when it should go only to the hip) or a loop in Constraints. Anyhow, even that’s a guess considering the amount of info you left out. A pic or a .blend works wonders for my inability to decipher the English language.
