Cannot drag and drop table

For some reason I can no longer drag and drop a table from the devart database explorer onto the designer. I have my edml file checked out, have the appropriate permissions on the db table and the table doesn't already exist in the model. I can't seem to drag anything over anymore.

The only change I can think of recently was installing visual studio 2010 sp1 and a new oracle client (11.2 release 3). Looks like v 2.80.136.0 ver of entity developer.

Any ideas? Screencast at http://dl.dropbox.com/u/235508/DevArtEd ... agDrop.avi

I have just performed a test using VS 2010 SP 1, Oracle Client 11gR2, and Entity Developer 3.20.104, and succeeded.
Could you please upgrade to the latest 6.10.126 build of dotConnect for Oracle?
Please let us know if the problem persists.

Unfortunately the issue remains after upgrading to the latest

One thing I noticed is that if I open up the edml externally in the Entity Developer app, it does let me drag and drop from database explorer. It just will not let me from inside visual studio.

I tried disabling some extensions thinking maybe there is some incompatibility there but so far that hasn't helped either.

On a hunch I attached another instance of visual studio and got the below exception when attempting the drag and drop from database explorer:

System.InvalidCastException occurred
Message=Specified cast is not valid.

This is a naming ambiguity. The Database Explorer you are trying to use is associated to OraDeveloper Tools. Open the View->Entity Developer->Database Explorer window, everything should work OK.
We will change the naming in one of the future builds.

Oh gheesh. Haha. Thanks. I didn't even realize DevArt had two Database Explorers and not sure why you guys would and if so why they'd be named the same. In any event that was the problem and hopefully future builds won't have this confusion as much.
