Visual Studio 2010 Datset Designer & ODAC 11.2.0.1.2

Question

When I drop a table on the dataset designer it can hang up to 10 minutes before finally adding the table.
This gets even worse when trying to add a new query to a table. It can hang for up to 1 hour.
I checked activity in Oracle and it is moving since it ends up adding the query. There is very little activity on the database.
I followed what an other thread recommended, use filters and reduce what objects the userid sees. I did that and in fact it can only see 10 tables and one package anyway.
What can be done to correct this issue?

Christian,
I just saw your reply to my post.
I found that the designer slows down when I remove the schema name from a sql statement in the designer view.
If I had Select ACCT_ID from AGG.TABLE_NAME it updates quicky. If I remove AGG. then update the sql statement in the designer then click OK the time it takes to update can vary from 1 minute to at times 1 hour.
I have filters in place to only look at the AGG schema, and only packages, and tables.
I have not seen the issue of the designer running over the link and querying another database again.
But for sure removing the schema name AGG.Table_NAME from the front of the table slows down the designer to a halt.
Here are some of the cursors that are running after I removed the AGG off of the table name before clicking OK.
