Page not loading

Hi,
I have a weird issue in that when I click through from the sites home page to any other page, nothing seems to load. If I click again, then it loads without a problem. If I switch supercache off, the problem goes away. I thought it might be our CDN, but if I disable that and re-enable caching, I get the same weird issue. It’s almost as though the browser isn’t recognising the url until the second click (when supercache is on).
At the moment I have caching off, but I will do some testing over the weekend to see if I can narrow it down a bit more, but I wanted to report this as a potential bug.
Actually, it’s worth noting too that I had to use a private window to see this as it seems that if the page is in your browser cache, it loads fine with supercache on.
Cheers
