Hi Naomi.

>I was able to setup initial width and height of the containers to cover the page (setting this in run-time in code seems to be ignored). So, I open the form, click on these two pages, resize the form and the containers resize OK when I switch between pages.

But now the containers on these two pages don't occupy the whole page - they look like their initial size. If I close the application and re-start it, then the form starts with its original size and I can resize it and everything works correctly.

Make sure you set Anchor to 0 before changing the size and position, then restore it.
