Browse Data & Parameter flds no longer fully populated after upgd SQL 2005

Question

I upgrade our SQL 2000 Server last weekend to SQL 2005 (sp2).
Now our Crystal reports that access SQL data are not working correctly. Parameter Fields are showing little to no data, where before the upgrade we were seeing many more rows in the list.
Digging further, I looked at the fields used for the dynamic LOV. If I use Browse Data on those fields I am seeing the same lack of data. One "Browse Data" that would typically return 80 items now returns 3 items. In that report the data field is DateTime. In another report, the field is string.
I am also seeing an extra check for User Name and password before getting to the Enter values screen for the parameter.
I am using Crystal Developer 11.0.0.1994. It is happening on multiple PCs. I tried with both the original SQL ODBC Driver and the newer SQL Native Client ODBC driver, with the same result.
I've looked at this for 3 days with no luck. Any ideas?

Full SysAdmin rights.
I use a dedicated ODBC connection and have tried both "SQL Server" odbc driver and "SQL NativeClient" (2005) odbc driver.
If I go to Crystal, to the Field Explorer, to the one of the fields, right-click and "Browse Data..." I get two results (I expect 82 results and have seen that in the past.) If I paste the query from Crystal, Database, "Show SQL Query.."  to SQL Server Management Studio, I see the full, correct results.
In one example the field browsed is called "PeriodEndDate" (DateTime). A dynamic Parameter Field was created accessing this field. Here is the security curiosity...refreshing now asks for the user login each time "Prompt for new parameter values" is selected. It used to ask only the first time. The Crystal: Data Explorer" shows the current connection logged in ok.
The two issues may or may not be related. Certainly if #1 were fixed, dynamic parameters would return the correct results. Even if it asked for the password each time.
1.) "Browse Data" returning a smaller result than normal.
2.) "Parameter Prompt" asks for Server Name, Database Name, User Name, and Password on
     each refresh selecting "Prompt for new parameter values".
