two totally unimportant bugs, a log file would surely be useless

A wonderful program, I am using the latest version.
After years of suffering with CuteFTP and Filezilla, I will never change again.
So many clever features I can't begin to list them all!
My two complaints:
1. Preferences...confirmations ... overwriting of files.
the checkmark in this checkbox disappears every few weeks. I suddenly notice that files are being overwritten without the chance to confirm and I have to reset the checkbox.

2. When deleting folders in the remote directory, the program asks "Are you sure you want to delete the file 'xyz'? It should ask "Are you sure you want to delete the folder 'xyz'.

Thanks for your report.

Would you be able to run a debug version of WinSCP to capture the problem?

I have sent you an email with the debug version to the address you have used to register on this forum.
