I was using a friend's computer.
I created another administrator account while I was on her administrator account, so when she woke up, she can go on using her own account without interrupting what I am doing -even mistakenly- on the other account.
I wanted to start a program, and the program told me that it was not licensed. I switched on to her account and started the program and saw that it was licensed and started without any problems.
Why would this happen?
Both accounts were logged in by the way.
And I also were able to hear sounds from her account such as message income, etc. while I was on my account. Is that normal behavior?
