MySQL Reconfiguration problems.

MySQL has some bugs, may be a bug, i am not sure, may be my wrong configuration.

if do reconfig, it will get error during excuting the details, actually in starting the service.

after do some research, i found a related answer as below. in today's case, it should be the old entries still in the registry.

Obviously there are some bugs, which might interact with each other:
a) Pathnames, as proposed, with included blanks (and probably dots, etc).
b) A security/acl issue when trying to alter the security settings.
c) When there a old entries in the registry...

Hopefully, somebody of MySQL AB will recognise this to be a problem, since this is a annoying bug. The follwing receipt helped me on both 'essential' versons, MySQL Vs. 4.1.9 and 5.0.2, respectively.

Hope, it helps! ... regards, A.N.
