Internet Explorer 9 is always failing when I try to use it to upload to alfresco 4.0.d community edition (running on tomcat).
I typically use firefox or safari and they work fine but I have a few other users who prefer IE9. Any solution to this? Is there some setting I need to tweak?
It might be an IE security setting. Try to register the URL of your alfresco share installation as belonging to the "local intranet" in IEs security settings.
