IV 2009 - When opening a large assembly I find that in some LOD the part priority selection tool does not work on all the part in the subassemblies. Some subassemblies will allow a part to be selected and others when you hover on a part to select it it selects the entire subassembly. Using the same assembly as IV 2008 (migrated) and in IV 2008 it works perfectly. I can select any part no matter how deep it is in the file structure. I am actually not sure if file size matters I just noticed it as we are just now starting to use 2009.
