Access Forms won't add or update records

Hi,
I have a problem using an Access front end connected to a MySql Database.
I test UPDATE on one small table with a VBA procedure, using DAO
sql = "UPDATE tblFormateur "
sql = sql & " SET Prenom = 'Werner' "
sql = sql & " WHERE Nom='HEISENBERG' "
The first time I run the query, it's ok.
But if I run the same query, without changing the value,(keeping Prenom = 'Werner')
I get an error message saying that the query has not been executed,
due to a lock violation.
If I run the query again, but with a different value, e.g Prenom = 'Peter',
the query is executed without error.

On the other hand, If I do the same experiment with ADODB,
I do not get any error.

One can say: let's go with ADODB!

The problem is that the Access front-end Forms use DAO, not ADODB!
So all the forms won't be able to either add new records or update records.

Did you experienced the same issue?
Are there some parameters of the ODBC driver that needs to be set?

Thank's advance for any help.

Windows 1
Access Office 365
ODBC connector 8.0 CE
