Focus issue with middle and right click in 5.7

Summary

I have just started using Unreal Engine 5.7 and encountered the following:

After right or middle clicking inside of the scene viewport, the editor will not let me use any options of context menus / popups outside of the viewport.

If i then right and middle click (depending on what i pressed inside) outside of the scene view that seems to release this lock of that specific mouse button, allowing me to use context menus again.

The issue is that I use middle and rightclick a lot to navigate around the viewport so this is a constant issue.

I have confirmed this is not the case in UE 5.6.1

Additional Notes

I am rightclicking outside of the viewport in the video everytime before it works again

I’m having the same issue on 5.7 as well. It also affects the blueprint editor, making it almost impossible to work with.

I checked on a different computer and that didn’t seem to have the issue so I’m assuming there’s some specific software that might be causing the issue, though I’m not sure what it is. I’ve tried ending different processes but it keeps happening.

Hopefully there’s a fix, but I’m gonna keep messing around with my PC to see if something works in the mean time.
