Hello,

the pagecontrol also behaves erratic in many ways when at least one
tabsheet has its tab hidden. For example, some tabs cannot be clicked
on and the contents of several tab sheets is shown at the same time
one over the other.

Probably a Carbon-specific problem?

I guess I will take a look at the Carbon sources. Again, I would be
grateful for any hints.

Cheers,
Tobias
