Hello

I have commented on this before and I believed is was solved, however the issue still continues each time I load my site upon loading my portfolio which I have set to full width 3 column, I'm getting large gaps between thumbnails, whereby there may only be one image on a line instead of three?

Initially I thought it was an issue with the cache but it happens each time I load the site, however refreshing the page sometimes works but not always, also clicking 'all' in the category menu fixes the issue, but its upon loading the home page each time that the gaps appear?

Any ideas?
