Sportman13, I'm not really sure what else to tell you. You keep asking us to get back to you, but we've given you all of the information we have already. We understand that you're disabled, but at the end of the day it shouldn't affect how you're using a calendar on the computer.
Most calendar's operate in the same fashion and we have given you all of the info we can possibly find on them. We have also made our personal suggestions (which ones we would use) quite clear as well.
Now, it's up to you to make a choice on which calendar to use. We cannot make that choice for you.
