Admittedly my ISP is slow, but I only have this problem with this page on the website. When I try to move from Newest on the CP page to Progress, the page often fails to react. I've now got round this by bookmarking the Progress page and putting it on my bookmarks bar. It now opens that quickly and without problems. Maybe this is a specialised problem, compounded by a slow ISP, but it does no harm for you to know about it.
