Raster layers are special and have their own weird behaviors. By default all raster layers open with pre-set zoom display turned on. You'll have to turn it on or be zoomed in to the right level or any new raster layer added will not be visible. Also, the FIRST raster layer open in a map controls the coordinate system. This isn't a problem when you are displaying several raster images that use the same system, but if you try to display two raster images that use different systems, it won't work well. And worse, it *may* look okay, but if you then try to lay a vector layer on top of them, you may see your vectors warped drmatically. > Right click on map window. View all Layers.

(Click 'Zoom' in the lower left corner of the status bar and choose 'Cursor Location') Are the two raster images actually anywhere near each other? Are your maps correctly registered? (i.e. are the corners of your map where you think they should be?) - Bill Thoen --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 14887
