Dear all,
As you know, it's up to use specific task lists files (stored and shared and backed in folders by names).
You could retrieve and re-open the latest task lists, using:
A- Re-open ToDoList and then with all of previously used files
B- If you have pinned ToDoList to your Windows taskbar, you could right click on this ToDoList icon to choose the -recent or pinned- task list file you have to re-open (the list of files depending on the size of your screen...)
Kind, B.
