That's really hard to tell... I ran update-xastir, which should get all the 
latest and greatest cvs updates. The only way I know to tell how old Xastir 
is, is to look at the timestamp on the file. The Help | About section says 
1.4.2.

The starnge things is that I get the occasional snapshot that works. I think 
I have narrowed down the problem.

I have the Toporama 50k image with a raster image on top of that, then a 
couple shapefile layers on top of that.

In that configuration, I get these errors.:

convert: Improper image header `/home/jewen/.xastir/tmp/snapshot.xpm'.
convert: missing an image filename `/home/jewen/.xastir/tmp/snapshot.png'.
System call return error: convert: /home/jewen/.xastir/tmp/snapshot.xpm -> 
/home/jewen/.xastir/tmp/snapshot.png

However, curl timed out, and I lost the Toporama 50k layer. Poof, I now have 
a snapshot of the screen.

It appears that convert is having an issue with the image header in the XPM 
file. Why would having the Toporama 50k layer on screen cause a problem in 
creating the XPM file?

I just turned on the Toporama 250k layer instead of the 50k layer, and I am 
now getting the same error.

I tried getting a really busy map in the USA, and making a snapshot of it. A 
simple Tigermap screen worked, but when I asked for all online maps, and 
then a snapshot I managed to kill Xastir. I don't know if this is 
coincidence or not.
