Hm, that doesn't sound right. Could you send me a (small?) program where
you see this behavior (and how you run and exit the program) so I can
see this myself?

No. Only if you create one yourself in the program. But it seems you
just use efSet, right?

Please send me the program and if I am able to reproduce this, I'll fix
it.
