DVDStyle issues, help please!

Hello. I want use this software to create DVD, because is really simple and I can make nice menus without lots of work. But I have some issues, maybe you can help me…

  1. I make a VMenu and a title menu (simple one). VMenu works nice but title menu dissapears in 2 seconds dvd is played, jumps abruptally and I cannot select any chapter.

  2. When I tried to select those “buttons” while DVD is playing on my PC, they appear if I select them, but when I don’t, nothing on the menu, just the background, why is that?.
