Screen switch-off is interrupting downloads

[Eichhörnchen]

I'd like to hear whether or not others have had this problem. When downloading stuff I have to agitate the mouse from time to time to stop my screen switching off, otherwise when I turn it back on I invariably find that the dowload was halted at the time the screen went off.

Annoying enough, but now I've had a large mod download interrupted in this way and been unable to resume the download because the 'resume' button doesn't work. Every time the screen goes black the download stops and I get the message "the download was interrupted". Easy to fix? Go to the display settings, right? Well you try finding them in Windows 10... I had to get the answer from bloody Youtube... every new version of Windows seems designed to make formerly simple tasks like this almost impossible.

Well I believe I've turned off all screensaver and sleep activity and the dowload has been started from scratch (about the fifth time now) so we'll see what happens
