While this is generally sound advice (and when using PICs I like to use minimal external components just because) there are cases where you may want a simple external debounce. In particular, if your switch feeds either a timer input or a pin with interrupts enabled. Usually you wouldn't connect a mechanical push-button to either of those, but you may be connecting something on a longish bit of potentially noisy wire, and a simple RC filter is worth including. But in this case Byron's absolutely right.
Anyway, good to hear that Maxim has sorted his problem.
