Unreal Engine 4.13 Freezing when Minimised

I’ve been having this problem for a while now on my home computer and I’ve tried all I can think of to fix it (updating graphics drivers and the likes).

Whenever I’m using UE4, it’s running fine and perfectly smooth (I have a 980ti with 32GB RAM). It’s never freezes while I’m using it, even when building or compiling or anything like that.

However, when I’m working off UE4, with it still open in the background (even if it’s just on the second screen), often when I go back to UE4 it’s frozen completely. My task manager says it’s still open and running and responding but it’s not doing anything at all. I can’t slick a thing.

I can’t just solely work on UE4 as I need to keep updating textures and models so I was wondering if anyone knew something I could do to fix this? Thanks.

Since disabling auto-save, the problem seems to have stopped. However not having auto-save on could be a problem if the engine decides to crash otherwise. Any help would still be appreciated.

I take this back, problem still persists…
