The Deployed option, as you may have surmised, had absolutely nothing to do with whether or not your sliders work. And, in fact, Deployed has no impact on slider functionality at all. But sliders can be disabled by setting Enabled->False. This is a useful feature, as it allows a continuous display of controls, but temporarily disabling them in cases where the controls are irrelevant. This is quite common in user interfaces generally, and there's nothing strange about how Mathematica does it. What is strange is why you should have had to set Enabled->True explicitly. To understand that, I'd have to see the code. Enabled is set to True by default, and unless you've somehow changed the default settings, it should not be necessary to explicitly set it to True. In general, the Deployed option makes an output act more like an interface and less like a raw bit of output. This means, for example, * Random bits of static text are not selectable or editable. In most interfaces (imagine a dialog box in any program you used), you can't go about selecting bits of text and rewriting them unless that text is inside of a control like an input field. * Graphics are not editable. You can't double-click to get inside them. You can't select them and resize them. You can't take take 3D graphics and spin them around. The graphics, like the text, are part of the background. * All controls remain active. There are, in fact, other options you could have used to achieve the above effects, but those other options would have messed with the controls, as well. By using Deployed->True (or the Deploy[] function, which basically sets Deployed->True), you get controls that work as they should while everything else remains a fully inert part of the background.
