When you close Backup4all, it saves the last window position. If you used multiple screens and now one of them is missing, the Backup4all window will be open on its last position.
In such a situation, follow these steps to get the Backup4all window visible again.
- Close Backup4all.exe from Task Manager
- Go to "C:\Users\<user name>\AppData\Roaming\Softland\Backup4all 9" and rename the "Layout.ini" file to something else.
3.Open again Backup4all. It will be open normally.
