privileges not updating

[me]

hi everybody,

i have a strange thing going on - i'm trying to update privileges on 
some databases but it doesn't happened - even after flush privileges - 
according to the manual the changes with GRANT an REVOKE should take 
effect immediately but they don't. i'm using command line....
also if i create a database, grant privileges on it and then delete the 
db if i check grants - it still appears...

what might be wrong? where should i look?

the mysql is 4.0.13 on a redhat 8.0 box...


thanks...
