there are some issues using Piwik with IE9:
Open Flash Chart IO ERROR Loading test data Error <a href='/2032'>#2032</a> This is the URL that I tried to open:../data-files/bar-groups-with-nulls.txt
Maybe the issues are related to IE 9. Just wanted to mention them.
Happy new year!
Marking as a dupe of #1728. We're too late in the release cycle to regression test the ui, so this is deferred to 1.2.
