There is no provision to automatically send the filter port message as 
part of a logon to tier-2 port 14580 (the user-defined filter port).  
You have to manually send a message to the server after logon to enable 
the filter.   If you get disconnected or the program switches to the 
alternate (fallback) server, nothing will be received until the message 
is again manually sent.   Not good for unattended operation.   Note that 
this failure won't affect the ability to send stuff heard off-air TO the 
APRS server; only to receive FROM it.

[ APRSplus and UIview both support storing and automatically sending the 
filter port message as part of the initial server connection process.  ]

This is primarily due to the resource-hogging sluggishness of MapPoint 
itself, not the application that connects to it.  The same problem 
exists with APRSpoint, or even MapPoint running standalone as a moving 
map GPS display.   In general, MapPoint isn't really usable on anything 
less than about a 400-500 MHz P-II or higher - the scrolling and zooming 
will just be too slow.   

Interestingly, the  nearly identical-looking  MS Streets & Trips 
(feaure-limited "consumer" version of MapPoint) is quite usable on 
lesser machines.  Unfortunately, there is no APRS application that can 
effectively use Streets & Trips. 

MapPoint and it's sister Streets&Trips are among my favorite mapping 
apps, due to the rich variety of information overlaid on the basic road 
maps (national park outlines, dry river beds, Indian and military 
reservation outlines, excellent closeup detail of freeway exits and 
interchanges, etc) but they do need to be "brute forced" on really fast 
machines to be responsive.
