Gaming Mouse

Hello,

no important question, but I would like to know one thing. Why my Gaming Mouse with lots of Buttons is a very comfortable Tool working with Photoshop, After Effects, 3ds MAX and many other Applications … but not with Unreal Editor? The 4.7 Version accepted any shortcuts send from Mouse buttons (not Undo and Redo), but the 4.11.2 ignores everything. Is there a technical reason for that?

Best regards
Hirk
