How do I make a button to NOT stop my slide?

So, I added some in-slide controls, firstly with click boxes but as my superior wanted them to have a hover effect, so I made them as image buttons. The thing with buttons is that I don't see an option to actually "not stop" the slide, so everytime it reaches the end, it stops and you need to advance manually (and that's not ideal, at least for the first couple of slides). I'm pretty sure there's an option to disable this and make it advance regardless of the button being there, but I'm not sure where it is.

Can somebody help? Btw, I'm running on the latest version of captivate.
