Hi Rudy,
I’m still encountering this issue UE-43213 with UE4 version 4.17.1 and Win10. UE4 is basically unusuable for me on a touch-screen laptop. It’s double-clicking for every touch in the editor. Checkboxes instantly revert themselves when touched. File menus instantly close themselves when opened. Expanded sections instantly collapse themselves, etc.
Could you please mark UE-43213 as Unresolved and take a deeper look into this issue? Let me know if you’d like any additional information.
