Hi,

Sorry it took me so long to get back to you.  I was using the
DataEnvironment to make the dataconnection. Yes i menat DBGrind, sorry about
the confusion.. The errors only occur if i am using a view with server side
cursors. If i change the connection to a table or client side cursors, then
everything works as expected. If you want me to try anything let me know...
I pasted the last bit of information in form the ODBC Log File..

Also here are the results based on cursor type.
Table: All cursor types  and locking work fine.
View: Client Side Cursors Works like a charm.
View: Dynamic cursor type with server side cursors and pessemistic locking
returns 0 records
View: Static cursor type with server side cursors and any readonly locking
returns all records and then dies if you try to scroll with the DBGRid(also
dies with CommponentOnes True DBGrid. 


This is the ODBC log file right after a crash with the Static Keyset with
serverside cursors and readonly locking.
