Ever use the georeference toolbar to register a raster image in ArcMap? I think most of us have used it in our lives and a small change in how 9.2 handles it might cause problems with users still using ArcGIS 9.1.

ArcGIS 9.2 no longer will write a tfw (world file) after georeferencing. Instead ArcGIS 9.2 will only write a .aux.xml file, which contains the referencing data. So why is this a MAJOR problem?

ArcGIS 9.1 cannot read the reference data from the .aux.xml file. For some reason ESRI Developers decided that this was not a needed feature (even though all their documentation (even 9.2 documentation) says that a world file would be created.)

The good news is that this issue will be addressed at the first Service Pack (I was worried that there wouldn’t be anything to put in that first service pack myself)
