Unfortunately, I don't recall exactly what it was I edited to fix this after the upgrade - I thought it was the mod_cbadmin.xml file, but I'm not sure exactly what I did when I edited it (or on which site I did this) last May.
I have three remaining sites still running CB 1.9.1, and I had forgotten about this little glitch that happens when I update to 2.x. Now I can't do much because the CB menu covers up most of the page.
Keep in mind, I didn't have a CB menu set up in the Administrator to start with, so I don't know why the update to 2.x enables it AND has it set to display like this instead of as a drop-down like the rest of the menus.
If you can give me a bit more specifics as to which file to edit under /administrator/modules/mod_cbadmin/, and what to change, I'll be sure I take care of it on the remaining sites so I won't get crippled like this again (all my sites will be done, but I may get hired to fix other sites in the future).
Thank you,
Ernie
