Anyway thanks for help 

I also have Archicad version 28 with all updates. So how can I permanently disable the information center in this version of Archicad?

I agree with what my colleagues have said, and I would really appreciate it if Graphisoft could disable this feature in one of the next updates to ArchiCAD 27. It's completely useless and impractical. Why force improvements to something that already works flawlessly?
