Hi paulus.v,

Thank you, again, for your new suggestion.
I'l try it, on Monday (I have just open your reply, today - Saturday), because I'm at home now.
My CHCF IS set to SEP, now.As to Cd1, it must be either tEr or LOC, I'm not sure.
On Monday I'l check it and change it, if necessary.

Best regards !
