Using PB 12.5.2 an PB 15 Beta
If I insert a standard tab control on a window, I can rightclick on it and add tabpages or userobjects as tabpages.
If I insert a control directly inherited from a tab control, the 2 options are greyed out ! (see picture)
I don't recal this behaviour in previous versions of PB.
Why this limitation? Could it be suppressed in PB15?
