One view in a drawing is missing parts of an assembly 1

[esull111]

I have a drawing with four views. The base view is not showing all of the parts in the assembly, but the other three views do show all of the parts. I have checked to make sure none of the components are suppressed, and that it is in the master representation. Does anyone have any ideas?

Are these missing parts imported files (step/iges) files by chance?
Is the associative view button checked? (The chain link looking icon in the edit view dialog)
Are these missing parts maybe reference parts?
Are you current on graphics card drivers?
Have you tried placing another base view of this assembly to see if the parts show up then?

They were step files and the associative view button was not checked. I checked it and everything is in all of the views now. Thanks for the help.
