I can't tell if it's the image that's low resolution, or if something's missing..? I don't have a BI 4.0 currently running to compare, but I know I haven't seen any issues with the toolbar myself with a standard install using Tomcat.
What BI 4.0 SP &/or patch level are you on?
[Edit] - whoops, see that you're on SP05, sorry about that [/Edit]
Is this WebI Rich Internet Application or WebI Rich Client?
If WebI Rich Internet App:
- Are you seeing any script errors at the bottom of the browser?
- What application server are you using?
Thanks,
Carly
