Right you are. That's why I only change one variable at a time to see if it solves the problem. Then I will know exactly what caused the problem and maybe how to prevent it again. Having a problem solved by changing more than one variable prevents one from knowing what the problem was and how to prevent it again in the future. Simple diagnostic rule - only change one thing at a time and see what difference it makes before changing another.
