Naomi,

Thanks I found the reason: The original programmer had a habit to code:

if not used('mytable')
use mytable in 0
endif
select myTable

than do some lookup or other things and at the end:

use

to continue with other coding.
Grr
since he opens tables always with if not used(' etc. I could simply remove the closing use

Thanks for support
Rgds,
Koen
