LaTeX.org

Ok, solved. I uninstalled Acrobat Reader and installed SumatraPDF

update: I uninstalled Lyx and Miktex, removed manually profile folders and reinstalled them. It works until I add a frame (return, BeginFrame, name of frame, return, content of frame, return, EndFrame). I must search for the pdf in %temp% folder every time. Very annoying.

Well, Lyx helped me a lot. Yes, it's not so powerful if you need something more, but for what I need it's enough. I think Lyx is a good compromise between Office (or Libreoffice) and Latex. For now it's a good tool for the casual writer and a good latex "tutorial" if you do "view -> view source ...

I don't know why, but after a while I tested it, Beamer class doesn't work anymore. Now if I create a simple Beamer document with title only:

if I compile it in PDF, Acrobat Reader asks me the language (?) and shows me nothing... but in %temp% the pdf exists!
Yap shows me the DVI, but it gives ...

As title, the preview of math formulas doesn't work if in document settings I activate "Synchronize with output".

Emh. Ok, I misunderstood the image in koma-book manual, page 21. I thought the default margins is for binding, and BCOR is for extra binding. I don't understand why a default binding is not added by default: it is a book. Anyway, now I can proceed further

It seems interesting, but unlyckily I already submitted my work. If I need it in a future I'll try it. Thank you.

Ok, I found an error, but it don't work anyway.
I searched for the .bat but I didn't found it. I created one as specified in the Addtional feature manual. This is the output of the batch:

echo LYXCMD:revdvi:server-goto-file-row:C:\Documents and 1>\\.\pipe\lyxpipe.in
output: the same
type \\.\pipe ...

I didn't specified any BCOR, the settings are the default ones. Did you have the same output as in my previous attached pdf?

Done!
