OS X Build Progress Popup Focus

I’m having an issue where when I start a build or Launch on a mobile device, progress pops up in bottom right as usual, but if I click away from UE Editor window I can’t get focus back on that popup, which means I can’t click buttons within it.

It’s most apparent when doing a mobile launch, since Cancel button can never be pressed if I click away (like to look at cat pictures while launch builds).

I’m on OS X Yosemite and Unreal Engine 4.5.1 (on a Macbook Pro 13" in case it matters - so a relatively small screen)

Has anyone else found this?

Hi HypotheticalEric,

Sorry for delay in response. We believe this is part of a larger bug with notifications (UE-3805) which has been fixed in 4.6. If you continue to see this problem after 4.6 is officially released, please let us know. Thanks for your patience!
