PROBLEM
ArcCatalog is a stand-alone application, providing a tree view window to organize and manage information such as map documents, item metadata, geodatabases, and geoprocessing tools for ArcGIS Desktop.
In some instances, the 'Main menu' of ArcCatalog cannot be moved and docked to the desired location, even after selecting 'Reset' in the 'Customize' window.
Rename the ArcCatalog folder in the Roaming profile to reset the configuration to its original settings.
