I can type and then add a task by clicking on ADD TASK easy enough but the problem is when I go to add another task the previous task is still in the entry area even though it has been added to my task lists.
This has just started happening and I have no idea why. Quite frustrating as I have to delete the previous task before entering the new one.
Not clear why you think that you have to delete the previous task before entering a new one.
The interface is designed to show the recently entered tasks at the top of the list so that you can more easily view them, rather than have them get lost in the list. They will remain there until you go to another view or refresh the screen.
Same thing is happening for me. When I go to the "new task" window all of the info from my previous entry is there. Usually all of the fields are blank except for the folder field which is by default the folder that I am working in. Only that's not working right either.
