Poor performance is experienced when loading SDE layers. This can also occur when loading shapefiles with .PRJ files.
This is a result of additional checks made for the NADCON grid files. These files install in the PE_Grids folder under C:\Program Files\Common Files\ESRI.
Rename or delete the PE_Grids folder if NADCON support is not required for projections.
At MapObjects 2.0a, when the PE_Grids folder is not present, the checks are omitted and performance is greatly improved.
For more information, refer to ReadMeMO20a.doc in the \Program Files\ESRI\MapObjects folder.
