Yes, I did reindex but they do not show up in the map chooser.

I have the second condition. Will the absence of the dbfawk file cause the 
map not to show in the map chooser?

I understand now about the display of the raster maps, perhaps that is my 
problem or what caused the problems. I _cannot_ display the online 
toposerver map or online terraserver map at all now. If I choose one or the 
other, a blank screen with no watch showing and no info showing map loading. 
I can choose online Tigerline maps and also the online US and TX radar maps 
but they will not lay over top of the tigerline map. I tried changing the 
map properties for the radar maps as Tom suggested in his email with no 
success.

Sure would be nice to have the option on receive also...where is that 
feature wish list page??

Tom's response:

Also, if you're using raster maps and shapefile maps together, there is
a possibility (probability) that your shapefiles are underneath the raster.

If you turn off the online tiger and toposerver maps, do your shapefiles
show up?  If that's the case, then you just have to use map properties to
bump the layer number for your shapefiles up above the default of 0 --
if everything's at 0, things get rendered in alphabetical order.

That's the catch, I'm not displaying the shapefile maps in the map chooser. 
I'll have to get that problem worked out first.

Since these problems have started, now a new one has surfaced last night. I 
have the snapshots enabled but getting this error:

convert: No encode delegate for this image format 
(/home/Randy/.xastir/tmp/snapshot.png).
System call return error: convert: /home/Randy/.xastir/tmp/snapshot.xpm -> 
/home/Randy/.xastir/tmp/snapshot.png

The problem seems to be related as it is dealing with an image file.

Thanks for all your help guys!
