When I use UE I have a problem with buttons,
clicking button like “Add new” it does nothing(I have to click it many times and then it opens).
The same problem I have with right mouse button and with top panel(File, Edit, Window, Help),
these elements do not work at all. Besides this I can do nothing with Settings, Blueprints e.t.c
I have Unreal Engine 4.12.5
Windows 7 pro SP 1
