LyX ⇒ Problem with beamer

[tuvok78]

Hi, I'm a newb.
I have problem to set theme/layout for a beamer presentation
I create a new doc and so in document - settings, i choose "document class - presentation (beamer)".
Now I have to set the layout, I have some layout, .sty files, but I can't select these files..
Can someone help me?
Thanks.

Code: Select all
