Can't create window

Hi! I’m the beginner, but I haven’t found anything about that:
I use Win98 & BC++ 5. Everything is right unless I choose
SDL_INIT_VIDEO. Then application shows “can’t create window”.
Why? What I’ve to do? With everythnig else it works correct as
far as it’s possible. Haven’t any problems with AUDIO nor CD_ROM.----------------------------------------------------
