I recommend downloading the VFP9 refresh, it has a few updates to apps.
You can get it from here.
In particular the anchor editor builder is a welcome addition.
Once you’ve downloaded and installed, run up VFP9 and then DO the following:
DO HOME() + ‘wizards\anchoreditor.app’
Now go into a form or container and the builder is available to help you set the anchor property on objects.
