I have probably fixed it. The fixed version will be released within few hours. Please test it and let me know.
I tested it with both protocols and the failure was reproducible with scp and sftp independent if resume was enable or disabled
What protocol, SCP or SFTP? If SFTP do you have transfer resume enabled for the particular transfer?
Winscp Version 3.6.1. build 221
When I copy a file from remote to a local directory an the file is already in the local directory I get a dialog box. When I press copy then a new dialog box pop ups an ask to overide the file.
If I close the dialog box with pressing on the x button in the title of the window the File in the local directory is overwritten. I think this is a wrong behauviour.
The Answer of the dialog box should be count as cancel.
