When moving or editing the annotation, the annotation disappears. We are editing on a black background, so the text isn't just blending in to the background. The attribute table does not show any abnormality, but the "Zoom to Selected" option is grayed out. It can be selected in the table, but does not display in the display window. Anyone have this problem? Found any solutions?
Just in case anybody else runs into this problem and lands on this page. Try:
-- Repair geometry -- Rebuild the spatial index (use the Add Spatial Index tool)
The latter worked for me when features in an Annotation Class were disappear upon zooming in.
