A quick workaround in IE9 is to press the F12 button (while staring at the nice blank white page) to bring up the debugger/dev tool and click on "Document Mode" - then change the mode to "Internet Explorer 8 standards". This will bring up the familiar warning about running scripts, then click yes and walla walla bang bang abra-cadabra....your log will appear!
Yep, the XSLT has been updated for IE 9 in the latest versions of DevForce starting with 6.1.0.x. sorry about the extra work for you to see it until you update to our latest.
