Heelo, All!
Can someone please explain these results:

1) Open two VFP 5.0 sessions on the same machine.
2) SET EXCLUSIVE OFF, on both.
3) USE MyTable (any FREE table), in both sessions (same table used).
4) In one session, do an INDEX ON Expr TAG Expr - no problem.
5) In the other session, table is still modifiable. Try SET ORDER TO Expr - error: 'Table has no index order set'. Close this table with USE and try to re-open - error: 'File access denied'.

It's like the table went from SHARED TO EXCLUSIVE use in the first session, because of the INDEX command!

All ideas will be appreciated!
TIA
Mark
