I can understand how frustrating this would be for you. This could be happening due to plug-ins that are out of date. You should try to update your browser plug-in and see if that helps. The plug-ins that you need to update are as follows:
Adobe Flash Player plug in: http://get.adobe.com/flashplayer/
Java plug in: https://www.java.com/en/download/
Silverlight plug-in: http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx
