Thanks all for your reports.

I have added this bug to the tracker:
Issue 2469 – Failure when using options in button drop down menus on Overwrite confirmation box

I'll be sending you an email with a development version of WinSCP to the address you have used to register on this forum.

Chyba přístupu do paměti - TMessageForm::MenuItemClick

2026-10-12 12:42

Whe copiing from remote FTP do HDD, overwrite confirmation window -> click on chevron on "No" -> select "No to all" from dropdown menu -> error. If I hold shift and click on "No to all" - everything fine. I am using Czech mutation.
A moc děkuji za skvělý software
