The driver should work with MySQL version 4.0.x and the latest MySQL 4.0.14.

QC Bugs addressed:
1. 3731 - FIXED
2. MySQL Port - Support added

3.4504 - FIXED

4.1810 - Data truncation (Vendor issue)
MySQL Field.length=1024 for the second columns after describing the SQL "Show create table tablename"
and that's the reason for truncation.

5. 4689 - Workaround done.
Timestamp comes back as NOT NULL always.(Vendor issue)

Please read the MySQL API documentation

NOT_NULL_FLAG - Field can't be NULL and the flag is set in for all the following a SELECT is issued on the following 3 tables.

create table testtimestamp1( f1 char(10), fts timestamp)
create table testtimestamp2( f1 char(10), fts timestamp null)
create table testtimestamp3( f1 char(10), fts timestamp not null)

So, there is no distinction between whether a timestamp field is created as NOT NULL or NOT.
I consider this a MySQL bug. However, a hack has been added to fix this issue for the time being.

The following bugs are being investigated:

6. 1074 (dbExpress Components cloning connection and Rollback failure)
7.3782. (Issue with Quoting objects )
