[aprssig] WinAPRS 2.8.2 notes

[MLSproul]

>The easiest way I found to refresh WinAPRS maps when they go blank:
>
>1.  Run the cursor over the button area on the right side of the map window,
>and the buttons will show up.
>
>2.  Then, click on the "Show Altitude" button twice - Once to show
>the map and the altitudes and once to turn off the altitudes.
>


or just click anywhere on the map window and type "L"
