Dear Radina-Matic,
Thank you for your time and support. I am already using the KA Lite, my mistake was so simple that is kind of embarrassing: when right clicking on the icon I simple didn’t click on “lunch browser”.
I kind of thought that just by left clicking or double clicking on the icon it would start or that if I opened the browser and tyoed Khan Academy or KA Lite it would start.
I was so simple, I smiled and now I am using KA Lite.
Thank you very much for your follow up, tome and support
