Problem: ArcMap crashes or disappears when the Export Map dialog box is opened
When clicking File > Export Map, ArcMap crashes without warning
The ArcMap export framework allows developers and third party companies to create and register custom export objects for use within the Export Map dialog box. If the custom export object has defects that cause it to crash, the entire ArcMap application may crash or disappear without warning.
Some custom extensions have been known to consistently cause the problem. Versions 3.0.4 and earlier of TerraGo Technologies' MAP2PDF for ArcGIS extension are not compatible with ArcGIS 9.2.
Solution or Workaround
Uninstall any custom export extensions and try opening the Export Map dialog box again.
