I believe I already talked with you on the phone however just in case that wasnt you...

This definitely sounds like a debounce issue. Some switchs are pretty bad when it comes to that. Using an RC filter was the right idea but if you have to use such a large cap to debounce you may need something more. Please provide a simple diagram if the RC circuit and switch(s). I think a diode in an appropriate location can be used to bypass the RC filter when triggering the switch but remain in circuit when releasing the switch.
