Same here on my Passport. And with browser still open, when page is reloaded the content shows again for a second or two and then screen goes white.

You could ask cbc.ca about it if they provide a means to do so--and maybe you have--but I would expect they would blame the BlackBerry browser. In fact I would attribute the problem to the BlackBerry browser at this point. It could be something temporary because of something unintended that has been done to the site that might be corrected at some point. I have had that happen, where something weird happens for a while and then stops. (The delta.com mobile website gave me a weird problem earlier in the year that lasted for a few weeks and then resolved on its own.)
