Every time I sign in, Cengage says "Closing your previous session, please wait." And I have to close the whole window and redo it. Every. Single. Time. I do not have another session open, the last time I was on, I signed out. Then, while doing an assignment, I click on the ebook link within the assignment and it says "it appears you are signed in on another window, signing you out now." THEN DON'T PUT THE LINK IN THE ASSIGNMENTSeriously hate using cengage and it sucks not to have a choice.
