Changing location of key file keeps old location in memory

[Brian]

Bravo for closing the previous ticket without bothering to find the real problem here! Your last comment is patently false, 100%!!!

Moving the location of the private key file for SFTP login doesn't work.
I have several SFTP sites set up whereby the folder for their private keys changed from C:\ to W:\.
All of the sites work perfectly to log in and browse the remote folders. The problem occurs when I drag and drop a local file to the remote server. In this case, it tries to reconnect to the remote server using the OLD keyfile location.
You can see the error message "Skipping non-existing key file "C:\0_Work\".... in the attached copy of the message log.
