For years I have used a financial services website to monitor my investment\nportfolio ([URL="http://www.moneyextra.com"]www.moneyextra.com[/URL] )\n\nFor years with Windows XP/IE6 and later with XP/IE7 everything worked (and\nstill works) perfectly.\n\nI now have another machine running Vista Home Premium SP1 with IE7 which\nwill not work reliably with this website. When I view my portfolio, some of\nthe web pages are often incomplete - but sometimes they are complete.\n\nI have tried using the MS User Agent String Utility to emulate IE6 but this\ndoes not work predictably either. Sometimes when I use this utility the\nwebsite is incomplete - but when I subsequently open a new browser it is OK.\nIf I close and reopen the browser the fault usually reappears. The behavior\nis unpredictable.\n\nClearly there is some incompatibility between my Vista/IE7 machine and this\nwebsite. The machine works normally on other websites and the website works\ncorrectly with my XP/IE7 machine.\n\nThis is beginning to drive me crazy, please has anybody got any ideas on\nthis?
