I haven't tried it, but the latest Browser Compatibility guide says you have to use Compatibility or Quirks mode on IE10. It also says this is the default, but MS technet says it is only the default for Intranet sites. You can use the IE Developer Tools in the Tools menu to check which mode is being used. See http://technet.microsoft.com/en-us/library/jj822325.aspx for more info.
Nicolas, I've replicated this on a server of mine (2008 R2) with IE 10.0.9200.16618. This is due to higher security settings on the Internet security zone for IE installed on servers vs desktops.
FQDN of PeopleSoft is part of the Intranet security zone on the server.
I'm getting the enhanced security pop up right before the "Node Saved" modal window. It indicates content for about:blank will be blocked.
Thanks for your replies.
@Bob, I played a lot with Compatibility view/Quirks, but no more luck.
@Randy, you got it right. All was about this about:blank security setting to be added in "local intranet". That should be acceptable workaround on the server, since it's not used for browsing except to finalize the install. I should remind it for further references.
