since 4.11 mouse events don’t work when the cursor is visible. There is already a pull request about this ( https://github.com/EpicGames/UnrealEngine/pull/2207 ).
Could someone confirm whether or not Epic will address this problem in a Hotfix and if so, when? I need to see the cursor in my project…
If you don’t fix this, I’d need to look out for some hack.
