On Facebook, the bar at the bottom of the screen (chat bar) works only about 25% of the time. Other times I can click it and nothing will happen. Other certain things on Facebook don't work as well, such as the default uploading picture utility. It just continues to load the utility, showing the flower-circle-loading picture-thing constantly loading. I also can't tag people in pictures, as the list of people that comes up who I can choose from to tag doesn't load.
On ESPN.com, at the top of the page, near the logo, there's always several links to GameCasts of games going on at the time. When I click them once, the usual "IE has blocked this popup" bar comes up at the top of the page, so I tell IE not to block it. After the page reloads, I click the link(s) and nothing happens. However, when I go to the "scoreboard" page on ESPN.com where all the games from a certain league are listed, I can click on any of them and they'll launch.
On MLB.com, on the left side there are links to MLB GameDay (similar to gamecast on ESPN.com). None of them work for me, ever. Also, on brewers.com, half the page doesn't load, such as the Video Corner on the right, pretty much everything under the "Next game" to the immediate left of the video corner, whatever is supposed to show to the immediate left of the "Brewers headlines", etc. Also, if you go to the scoreboard page on MLB.com, and choose a date from the past, you should be able to click the score of any half inning and watch that on MLB.tv for free. Nothing launches when I click it though.
I use Windows XP on an AMD Sempron Processor 3100+, with 1.50 GB of RAM. On my IE Internet Options, under Advanced, the only thing under the heading "Java" (use JRE 1.6.0_07 for <applet>) is checked. I'm not sure what other settings you'd like to know to help me solve this problem. My "security level" is medium-high. I use Symantec Client Firewall. When I disable it the problems still exist.
Thanks in advance for all your help.
