I just tested here and it works for me. I don't know what is
different. Maybe you unchecked "create default configuration file" in
the fpc installer.

Are you using Windows XP too?

If you focus in the positive side, you learned a lot about how to
configure lazarus =)

Also, the original answer by Joost was:

"You can find this problem in the bug-tracker. You can work around it
with 'TDataset.DisableControls' and 'TDataset.Enablecontrols' around the
applyupdates call. Or try fpc 2.2.2rc1 or any later version."

So instead of trying to configure Lazarus with FPC 2.2.2rc1 you coul
just have used TDataset.DisableControls ...

It surely won't be cross-platform, nor will it support unicode =P Also
it's probably a bad choice, as VB will probably wish that you use
Access instead of MySQL (unless you don't care about which database to
use).

But I do agree that Lazarus needs to improve when it comes to
developing database aware applications.

With the money from VB you could pay someone to fix all problems with
lazarus database apps connecting to mysql =P

I would go as far as saying that the only case in which I would
recommend for someone to use Delphi instead of Lazarus is if he is
developing Windows-only data-aware applications and he doesn't need
any of the other features of Lazarus (like being open source,
supporting unicode, etc).
