Does anything change if you edit the buttons using something like Photoshop or Microsoft Paint and make them taller?
Unfortunately, it doesn't fix the problem.
Do you know if there is a way that I can add a transparent button underneath my existing buttons/toolbar, rather than to the side?
Your response makes me wonder if you misunderstood me. Especially the bit about "transparent" buttons. Because that's precisely what I was suggesting. Add the "padding" you want, by adding some transparent area at the bottom of the buttons. That way the appearance should be that the buttons have some blank space below where the image ends and the divider.
At least that's what I interpreted you to be wanting.
I created new buttons with a transparent layer, but it doesn't seem to see the transparency. I was hoping that if I could insert a button that was only a transparent placeholder with no other content, then it might insert the space (if for some reason the layer was the problem in my original buttons).
Sorry, I guess I'm out of suggestions then.
To my knowledge there is no way the pages look at an image and simply discard the transparent part and position the image so whatever isn't transparent is shown. And it's always been my experience that the toolbar adapts to whatever height the tallest image button is.
Are you able to create a new project with just a couple of topics and use the skin causing you problems and send the project to me? I'd be happy to take a look at it and see if I can sort anything.
I went back in and added even more transparent space, and that fixed the problem. I guess 3px wasn't enough.
Thanks for your help Rick.
