Interesting. I was going to pick you up on assigning .Y. to the visible property, rather than .T., but I've since experimented and it seems that VFP is happy with this and interprets it as .T.

I didn't know you could do that. OTOH, I'm not familiar with WEB applications and maybe it doesn't work in that env.
OTOH, it might have been a typo?

All my forms are based on delayed initiation. I simply drop the container on the form at run time when the form is activated. I am using these containers in a web application which initiates the container and then calls the Rendering method which returns an HTML string representing a complete web form which is then sent to the browser.
