[Q] "The storage engine you selected is not enabled currently"

Well, I've just installed MySQL and tried to create a table using MySQL
Admin in the test schema. When I attempt this, the client responds with

"The storage engine you selected is not enabled currently".

When I click/acknowledge the error dialog the Table Create window is
displayed. Unfortunately, the window does not allow me to create a table.

As I did not, initially, enable InnoDB, just MyISAM, I went ahead an did so.
However, after enabling InnoDB I get the same error message.

On the other hand, using PhpMyAdmin, I can happily create tables (and rows
and populate 'em with data).

Here's the version details of the software I'm using:
MySQL Server - 5.0.41 (Community NT)
MySQL Client - 5.1.11
MySQL Admin - 1.2.12

Thanks in advance for any thoughts you might have...
