Everything is ok and x is not disappearing Since some time ago, I've started with MySQL so I don't know Workbench very well.

That little red x next to the number of the line that indicates an error does not disappear, even though everything is okay and I fixed what was wrong. 

A simple example: select * project where name='Anna' and I can execute it but x won't disappear unless I delete everything and type again. This is very annoying and I can't concentrate because of always thinking about what should be wrong.

Could somebody tell me what to do to fix this? :(
Sounds like it is a syntax check complaining:

select * FROM project where name='Anna'
         ^^^^  -- missing syntax keyword!
