PAGER PROBLEMS

See attached project.
Pager.zip

There are 3 Pagers.

Pager1 (red) is vertical.
Buddycontrol is Picture1, set at design time.

Pager2 (blue) is horizontal.
Buddycontrol is Picture2, set at design time.

Pager3 (lila) is horizontal.
Buddycontrol is Toolbar1, set at design time.

a)
When I start, only Pager3 catches the Buddy correct.
To assign the Buddies in Form:Load doesn't help.
When the Form is loaded, the CommandButton works to do it.

b)
Now let's resize the form manually.
Watch the Pager Buttons.
The Pager shows it's Button wrong.
It doesn't refer to the contained window size.
Also when we resize back and forth, this Button shows up at different window sizes.

With a toolbar as the contained window, it works ok.

Do I do something wrong, or is a PictureBox not suitable for a Pager?

Thanks
