If I understand your problem correctly, you want to choose Artists (no compilations) as your Browse By setting. If you are using some other Browse BY setting that includes Artist, such as the default Artist (overview) + Artist - which seems to be what you are using, here is what you do.
Right click in the left pane (the one with the folders)
Select Customize View
Artist should be listed in the Display these folders panel
Highlight Artist
At the bottom you will see a checkbox, No tracks
Click on this checkbox
Click Save as Preset
OCD will suggest a name for this preset, but you can type in any that suits you
That should keep Various Artists from appearing anywhere but under Various Artists. However any tracks by Eskimo Joe that are on a Various Artists album will not appear under Eskimo Joe anymore. I don't think there is any way in the current version of OCD to show just the Eskimo Joe tracks on a Various Artists album under Eskimo Joe. But if there is I would appreciate learning how to do it.
