Fausto,
Your choices are to use the NOFILTER clause in the cursor to force the SQL-SELECT to open a separate table (not a filtered version of Table1) or to always use the "AGAIN" clause

USE Table1 again in 0 alias Table1

The USED() command checks for an ALIAS not a TABLE so if your cursor is actually a filtered table then USED('Table1') will be .F. but you still won't be able to USE it without the AGAIN clause.
