• Due to changes ESRI has made to the ArcGIS ArcObjects programming language the 8.3 and 9.x versions of the Data Viewer are incompatable.
   
• Loading images with the DataViewer button will not work initially. Due to a bug in the ESRI software, the lyr files for image catalogs will not save the relative path that points to the images. So when you load the images a red excalmation mark appears next to it in the list of layers.
   
• After entering and zooming to point using the Enter Point feature in the Zoom section of the Data Viewer, you must click the back button twice, to return to the previous extent. This is because the code for the Data Viewer does the zoom to a point in two steps (center the coordinate on the screen and then zoom in).
   
• The Data Viewer and lyr files were created in ArcGIS 9.x and prior versions (8.0 - 8.3 ) will not be able to access the lyr files for the symbology. To get around this issue you can create your own symbology and add it as your own theme using the 'Add LYR' button.

If more problems occur with the ArcGIS 9.x MassGIS Data Viewer, please contact Michael Trust at (617) 626-1195 or email: Michael.Trust@state.ma.us
