I have installed PB2017 then migrated my old pbcode from pb12 to pb17. I found one strange error. In pb12 if we click any tabpage and if we have tabs inside that tab page by default it will open the first tab page but it is not happening in lastest pb17 it is displaying nothing untill we click the tab page. I need first tab inside that tabpage should be opened autoaticall once we clicke the main tab.
Kindly help in this regard
