This is related to new Excel 2007 behaviour and the second link provided by SIM worked, it gives you a downloadable FixIt program from Microsoft.
For those who already have the regedit open/quick fix, you simply replace the 00008 with 80000a00 to set it to open in the browser not externally via excel.exe.
This also works in IE9. HTH
