For lectures I am giving now I developed a special StyleSheet entitled "LectureNote". I, myself, and my students installed it into the directory
$BaseDirectory\SystemFiles\FrontEnd\StyleSheets. After that the LectureNote item appears under the Menu/Format/StyleSheets. All my lectures are written and saved in this style.
I expected that all my lecture notes created within this StyleSheet on my desktop will be automatically recognized by my laptop as well as by those of my students (where this StyleSheet is installed in the directory mentioned above).
Alas, it is not the case, and we need to go to Menu/Format/StyleSheets and click LectureNote each time after the lecture notebook is open.
My question: Is it possible to do something to force Mma to automatically recognize the StyleSheet in which the lecture has been created?
