.csv files no longer open in notepad

[Anke]

Hi 'all!! 
We updated to Windows 7 & IE 9 a week or so ago...we are on Cognos 8.4.1

Reports that used to open in IE 8 & Win XP that are .csv no longer open... I do not have any toolbars/ and popups are off, Cognos is in trusted sites...Excel 2007 format, HTML, and PDF open fine.  When I run a .csv nothing happens....when I run on my other PC, I briefly see the window (like how the Excel would flash with popup block on or popup on toolbar on)...

This worked fine in IE8...the only thing that has changed is IE....is anyone using IE9 and .csv's ???

Suggestions?
Thanks!!
Anke


X-posted in ReportStudio -- no answer, so I am thinking I have this posted in the wrong area...surely someone is using IE9 and is opening .csv files in notepad?

Is IE 9 a supported browser?
