650 Mobile Edge browser loads but displays blank?

[Warren_2185]

Every once in a while I get my 650's mobile browser Edge to load pages but they won't stay. If I "x" out to see multiple tabs at the same time, the new content for that window can be seen in the "tiny window view", so why doesn't it show up when I enlarge? I do a restart and then I can re-load the entire page properly. But, my question is, why did I loose he ability to see that page in the first place in Edge Browser?
