Gallery Block: Thumbnails line break

Hey all. I'm using Ishimoto, if that makes a difference:

I'm attempting to place a Gallery Block - Grid Style - in a blank page, and the thumbnails refuse to stay on the same line. No matter how many per line I choose, and no matter what padding I choose (or what crop on the images). They always break. For example, if I choose four per line, I get this:

x x x
x
x x x
x

And if I choose five per line, I get this:

x x x x
x
x x x x
x

etc.

I am not using any custom CSS on this site. I've ticked every box on and off and I know of (Lightbox, no Lightbox, etc.). I've adjusted the padding on the entire site, the width of the site, etc. Nothing can trick these images to stay on one line.

Any ideas? So grateful for any help.

Thanks so much, @Paul2009. I finally found an agent who helped. They suggested I removed all of my custom CSS, and it turns out that was the problem. I had added code to put space between images on my homepage, which applied to all images on the site, apparently. (Which is an obvious answer that I should have guessed, but I had completely forgotten I used that code.)
