Good info, thanks.  Guess it's not the only bug with current_schema. 
Found info on Metalink indicating that alter current_schema then
accessing views via PL/SQL is another possible bug being investigated. 
Whew, haven't totally lost my mind.

Which brings us back to Darlene's point of referencing the view as
schema.view_name or creating a synonym.  Those are the workarounds for
this problem.  Sadly, we're back to using synonyms for now...
