Hi
If it is doing it properly then it's a good feature, if accidentally it is a bug then please dev donot fix it, because "stains are good" sometime...

I used to download large files from hosing servers and recently noticed FDM manger resumes download from the server even after the VPN is disconnected. How does this work, since the IP address is changed (on my PC). Infact the servers (wesendit) has authentication protocols before a download is initiated.
