I’m encountering a rather specific and obscure problem when using software that allows me to control input of systems on my LAN (such as mouse without borders) and UE4. Everything works perfectly with the exception of the blueprint EventGraph, where right clicking always resets the position in the event graph. The point chosen seems to be relative to the host system’s “faux” mouse position (i.e., if i have my second system on the left, relative to host system, the point will shoot to the far left of the Eventgraphs center, and on the right if I position it window on the right.
This means I cannot use rmb drag to move around the EventGraph nor can I bring up the rightclick menu, making editing the EventGraph nearly impossible (Is there even a way to move the view position without RMB?)
I have no other issues within the editor itself or inside the PIE/Standalone game, both dragging and RMB work perfectly fine. Only the EventGraph appears to be affected.
I have tried several kvm-like software and they all have the same results.
I was able to replicate the behavior on 2 systems, both fresh windows 10 installs with fresh UE4 14.2 installs.
Has anyone encountered this issue or found a program that does not suffer from this issue? I have tried 3 programs so far and they all suffer the same issue with RMB and dragging in eventgraph.
