Periodically, when im closing various browsers or applications I get the\nfollowing messages for seemingly no apparent reason>\n\n"A Runtime Error has Occured.\nDo you wish to Debug?\n\nLine: 567\nError:'lastUpdateTime' is null or not an object\n\nYes No"\n\nIf i select no, it doesnt close. If I Select yes, I get another message.\n\n"Microsoft Visual Studio Debugger\nAn exception occured. Process will be terminated. (Exception address is\n00413E6C)"\n\nThis then dissappears and yet another message appears\n\n"An Exception 'Runtime Error' has occured in Script.\n\nHowever, no debuggers are registered that can debug this exception. Unable\nto JIT debug."\n\nI am using Windows Vista Ultimate with all security patches up to date. AMD\nAthlon 64 3200+ with 1Gb ram.\n\nAnyone help or is this just another one of Vista's many glitches????
