Right-click on the Notezilla
icon next to the clock in the task bar and choose Preferences. Click on the "Advanced tab" and enable the 'Stick to Windows desktop' check box under the section "Incoming notes".
However, please note that If there are multiple unread notes then Notezilla
will show small notification. Since multiple notes are unread, Notezilla
doesn't show all notes together on screen. So, go to Notes Browser, click on Unread filter on the left to view all unread notes. Now read each note so that all are marked read. After which, every note you receive will appear on automatically on your desktop.
