TPageControl with tabPosition to tpLeft / Right with Windows 95

I have a PageControl i set to tpLeft or tpRight : it works fine with Windows
NT 4.0 sp 4 but when run on Windows 95 the tab captions are blank... What am
I missing ? i suppose i need some DLL but didnt figure wich one after
numerous tests...
I'm using C++ Builder 5.0 sp1.
Thanks for your help !
