Hello, I have a two-step form that posts GET data to the URL and it has been working great for the past few years in FireFox, Chrome, Internet Explorer 7 and 8.

Here is how its being posted in the browser and works fine:
Code:
www.mywebsite.com/page.php?row2009_523=253.3&rowcagr_523=10.5&row2009_524=172.6&rowcagr_524=10.3&row2009_525=10.2&rowcagr_525=14.8&row2009_526=93.1&rowcagr_526=9.8&row2009_527=128.1&rowcagr_527=9.8&row2009_528=76.6&rowcagr_528=10.7&row2009_529=64.1&rowcagr_529=11.0&row2009_530=59.7&rowcagr_5
However, the new IE9 is posting the GET data as:
Code:
www.mywebsite.com/page.php?dataTableArray=a%3A29%3A%7Bi%3A0%3Bs%3A3%3A%22198%22%3Bi%3A1%3Bs%3A3%3A%22199%22%3Bi%3A2%3Bs%3A3%3A%22200%22%3Bi%3A3%3Bs%3A3%3A%22201%22%3Bi%3A4%3Bs%3A3%3A%22202%22%3Bi%3A5%3Bs%3A3%3A%22203%22%3Bi%3A6%3Bs%3A3%3A%22204%22%3Bi%3A7%3Bs%3A3%3A%22205%22%3Bi%3A8%3Bs%3A3%3A%22206%22%3Bi%3A9%3Bs%3A3%3A%22207%22%3Bi%3A10%3Bs%3A3%3A%22208%22%3Bi%3A11%3Bs%3A3%3A%22209%22%3Bi%3A12%3Bs%3A3%3A%22210%22%3Bi%3A13%3Bs%3A3%3A%22211%22%3Bi%3A14%3Bs%3A3%3A%22212%22%3Bi%3A15%3Bs%3A3%3A%22213%22%3Bi%3A16%3Bs%3A3%3A%22214%22%3Bi%3A17%3Bs%3A3%3A%22215%22%3Bi%3A18%3Bs%3A3%3A%22216%22%3Bi%3A19%3Bs%3A3%3A%22217%22%3Bi%3A20%3Bs%3A3%3A%22218%22%3Bi%3A21%3Bs%3A3%3A%22219%22%3Bi%3A22%3Bs%3A3%3A%22220%22%3Bi%3A23%3Bs%3A3%3A%22221%22%3Bi%3A24%3Bs%3A3%3A%22222%22%3Bi%3A25%3Bs%3A3%3A%22223%22%3Bi%3A26%3Bs%3A3%3A%22224%22%3Bi%3A27%3Bs%3A3%3A%22225%22%3Bi%3A28%3Bs%3A3%3A%22226%22%3B%7D&country_id=3&procedure_id=1&table_id=4&x=134&y=12

Any ideas why IE9 is now the only browser (no jokes please ) that is treating this GET data differently?
