[Xastir] maps

[Gerry Creager N5JXS]

Multiple map windows is (I think) on the list for Xastir 2.  For now, if 
you want a bunch of map windows, X-APRS does that... in fact, I've had 
it give me so many that it managed a kernel panic... Caveat User.

I've seen a similar problem with water poly's but I've also seen it in 
ArcView and MapInfo, so I'm not sure if it's our software or my data...

As for losing streets with area fills on, I suspect you have some 
polygonal areas that are being presented on top of streets that are 
getting filled.  Layering differently may change that, or you may be up 
the preverbial tributary without a manual rowing implement.

I have noted that layering isn't always a science, but it usually worked 
for me.  Stated another way, I can't get it to consistently cause 
problems I can document.
