just read this and haven't read forward yet, so maybe you have it now, but this sounds to me like you had an unexpected load / resistance imbalance. The added resistor may be fixing the problem, but I would look further to find the cause of the imbalance; you may just have to change the value of an existing pull up of pull down.
