Okay, I did a search for this, but couldn't find any recent posts with this strange issue. For me, some flash videos will load and others will not. Youtube works, for example, but other video site often give me a black screen with the spinning white "loading" message, but the video never loads. One thing worth noting: I've noticed youtube videos do NOT work when it tries to load an ad beforehand. However, if I refresh the page, the video loads, because I guess it assumes I've seen the ad once already, and therefore doesn't need to load it up again? I've tried repairing disk permissions, emptying the cache, deleting all cookies, and uninstalling and reinstalling flash. What might be causing this odd problem ? Thanks !
