No matter what I try, I cannot open TI V11 if I have two operating systems on my computer. The dotted line that opens the program gets about half way across and stops. If I wait like 15 minutes to a half hour it eventually works its way across and then opens. Strange!! Not the end of the world but with V10 it was fine. Is this the way it is supposed to be. Am I the only person who has experienced this?
