Hi, I'm working on a site in development with a client of mine. We're using WP 2.9.2 and RB Internal Links 2.0.11.
I do my work on a Mac running Firefox, and when I'm editing a post or page the RB Internal Links button is visible in the editor.
However, my client who works on a Windows machine in IE7, cannot see the button in the wysiwyg editor. We've tried this on a couple of computers, with a couple of different administrative-level logins, and the problem occurs in both places.
I have a bajillion other plugins and functions, but anything I can do to help troubleshoot this, please let me know!
