[V4RB] Multiple cursors on one database

I am continuing to have trouble with opening multiple cursors on the
same database, as I see others are from the notes on this mailing list.
1. I start opening one cursor as read/write:
curOne = mInflected.SQLselect("select * from INFLECTED",
EVCursorLocation.kServerSide, EVLockType.kReadWrite,
EVCursorDirection.kRandom )
2. Then later in the code I want to open a second cursor as readonly:
curTwo = mInflected.SQLselect( "select * from INFLECTED",
EVCursorLocation.kServerSide, EVLockType.kReadOnly,
EVCursorDirection.kForwardOnly )
Should I not be able to do this? The second cursor is for lookup
only, and any changes I might make to curOne don't affect my lookups
in curTwo.
If I comment out curOne, curTwo works, so I can only assume that
these two cursors are incompatible. This is a single-user application.
This happens in my application over and over. Is my assumption above
correct? Should I be able to open both cursors?
Thanks.
Bill
