Starting the WebTranceiver's JAVA app can sometimes be a problem. The following lists several Operating systems and browser configurations and some solutions: Mac OS Snow Leopard 10.6.8 with Safari: no problems Windows IE 6.0 under VMWare 3.13: no problems Windows XP and IE 7.0: Could not get JAVA to run Solution: Installed the Chrome browser and JAVA ran on it with no problems Windows 7 and IE 9.0: Could not get JAVA to run Installing the Chrome browser did not work Installing the Safari browser did not work Solution: Disabled all addons in IE-9 including JAVA plugins - now works well A cleaner solution would be to go through each add-ons individually to determine which combination is causing the problem but this works
