For a long time I was not able to navigate the site at all ... time outs ... pages not fully loading ... links not working. As I was using Firefox, I tried Chrome and Explorer to no avail. Very frustrating indeed. Reinstalled Firefox no good. Thought about a new install of Win7 but did not do so.
Flash Player for YouTube was not working either and would lock up Firefox. I uninstalled Flash Player and reinstalled it. Now everything is working fine. I am not as PC smart as you guys but WTF, or was it coincidence.
