One of the new features introduced with the latest release of ArcGIS Explorer Desktop (build 1500) is the ability to label notes. By default the title associated with a note is displayed as a tip when you hover over the note.

 

For point notes you can now change the display of the title to be shown as a label. Select the notes you want to label, right click, and choose Labels instead of Map Tips.

 

All of the notes will be labeled, but to avoid label conflicts the labels that are shown will vary as you zoom in or out. Surrounding labels will change to display the title as a tip for easy identification until the zoom level is such that no other labels intersect it

 

You can also set this by using the the label options in the Symbols group of the Appearance tab for notes.

Labels and Map Tips can be set for each individual point note, just select the one you want and make the appropriate choice from the appearance tab or by right-clicking to open the note properties.
