[Plugin: NextGEN Gallery] Thumbnails not showing up in columns in gallery view

Hello everyone,

in gallery view, all the thumbnails show up in one single column. I’ve set the columns to 5 in the plugin options, but all it does is group the thumbs into blocks of 5 rows each.

Here’s the gallery in action:

I tried adding a couple of fixed widths and heights to the CSS, but with no effect. Any ideas what I’m missing here? Any suggestions would be highly welcome.

Thanks in advance
Bjoern
