Plain session log won't help. We would need trace file from a debug log. I'm send it it to your email address.

OK. I have activated logging and will send when it happens again.

Thank you

Do you know under what circumstances does it "uncheck"? Or does it at least happen often enough that it would make sense to send you a debug version? So that you can use it and send me a log file, once the problem appears?

New to the forum, couldn't find a search facility to see if this has been asked before?

Title says it all. I have to keep setting the preference to confirm overwriting of files. It keeps un-checking itself?
