Malcolm,

You can Save the pgf.PageHeight and pgf.PageWidth from the original orientation, change it then adjust the pgf.Height/Width to match the previous .PageHeight/.PageWidth.

If your've got the screen space available and can leave like 27 pixels of margin on both the left and bottom then your controls should all just fit ok when the tabs change.

It can get more complex if you have enough tabs and the difference in size between the Height and Width is great enough you may end up with more than one row of tabs which would mean more page margin buffer would need to be maintained.
