ORACLE ODBC Instant Client 10 - trouble adding new connection

I have installed Oracle Instant Client 10 so I can create a new ODBC connection to a 10G server (currently using Oracle 9 ODBC drivers for other apps). I am in ODBC Data Source Administrator > System DNS > clicking add...I select my new Oracle 10 Instant Client Driver, click finish. The problem is: I am not able to select a TNS name from the drop down box. If I click the drop down box there are 4 options that look like greek characters. I should have my prod,test environments like I do for the Oracle 9 ODBC connection. I changed my system variables to include the path where my Instant Client 10 was installed (which has a copy of tnsnames.ora file). This fixed some errors I was having before this one but I still cannot select my prod environment with this new driver.

I have not done much with the "Instant Client" (that is new with Oracle10). I have set up some machines with the Oracle10 client that needed an ODBC connection to an Oracle10 database, but I just installed the full "Administrator" client even though I know that includes more than the minimum needed. When I tried installing less than that though, I couldn't get the Oracle ODBC client to work. We don't depend on ODBC for most of our work, this was just for a couple peripheral applications, so I'm not really an expert with ODB via an Oracle client (any version).

change your registry and change your local computer -> all_homes -> default home -> to the one that you just installed and run the odbc admin again.

I still want to be able to use my old Oracle 9.0 ODBC connections is there a way I can use both 9 and 10? Also, what do you mean by 'change your local computer' ?

I think that means: "change your ...default home -> to the one that you just installed".

Tried changing the default home settings in the registry - had no effect. Any other ideas how to get two different Oracle ODBC version drivers to work?
