I can't see the screen shot, but I think I know what it is. Mine does that sometimes with me. Is it still loading the site when it turns white? If so, go back, then go foward after the last screen appears, that always worked for me.
*Edit* OK, Now I see it. Hum... maybe it's the cookie problem? I noticed on mine that after awhile on this site, I can't see any pictures on anyother site until I delete all cookies and files and exit the internet, then get back on. (That's what I did to see that picture) Maybe that's the problem...
