I apologize for my English
I installed the pdf-embed plugin, activate the plugin and the button inserted in Article command {pdf = http: //http://www.mysite.info/images/pdf/storiasosjj.pdf | 100% | 500 | native}
unfortunately at the opening of the article pdf file is not completely open, but in a small 100x100 window.
Where is the mistake ???

best regards
Gianni
