Query execute thread cannot connect to Mysql

Hello all,

I am relitivley new to mySQL. I started by downloading from the mySQL site.
I then downloaded mySQL administrator and mySQL Query browser.
With my set up I got a user root with a specified password.

I created a DB(school) . When I log into mySQL Query browser with root connection, I see all my tables etc. I even see the information_schema.
I can select anything from anything.

I set up a new user (student)that has select, update, insert, create, drop, delete privileges on my new DB(school).

I created a table in school called courses and filled it with test data.

I created a new connection called stuconnect for my user student

When I log into query browser using student, I get into the query browser and I can see my school db, and courses table. I can however see the information_schema stuff to.

(I don't like that, I don't want users to have access to that information)

When I try and execute a query:

I get the error :

Query execute thread cannot connect to Mysql,

Am I missing something ???

Thanks in advance
