If you run AUSED(), close some cursors or tables, then you should run the function again to reload the array. (I'm not sure exactly "how" you are using the code, so it could be something else).

The code I showed you assumes you are using some sort of naming convention for you cursors (eg. cursor1, cursor2, etc. ... as you showed before).

Your 2 table approach is not practical because (without a naming convention) a cursor can look just like a table on the surface. For example, using the function DBF() on an alias returns the filename xxx.DBF for a table, xxx.TMP for a cursor SOMETIMES and xxx.DBF at other times (when the cursor is identical to the source table).

Using a naming convention is simpler all around. I usually prefix all my cursors with "TMP".
