I believe we're supposed to switch to TPageControl in- at the latest- 
0.9.30. I find I've still got some references to TCustomNotebook that 
I've got to expunge.

I'm not sure how aggressively Lazarus reported deprecated classes. 
Admitting sloppy practice, I'm starting to have a war on warnings etc. 
emitted by my code at least by inserting {%H-} tags in strategic places.
