Mac 4.10 Editor becomes unresponsive when displaying dialogs

When I do actions in the 4.10 Mac Editor that cause the editor to display a popup dialog, the editor can become unresponsive and the popup cannot be focused. I’ve also noticed it happens if multiple dialogs are on top of one another. In one example I selected “Submit to Source Control”, and the editor spawns two popups, one appearing to be a message, and the other a progress display. However, the two popups are immediately unfocused (hidden, even when the editor is minimized). If I switch active desktops, I can see the two popups appear briefly, but they disappear in under a second, so I’m unable to click them. At this point, the editor’s menus are responsive, but the UI is not. However, when I select “Quit”, the editor does nothing.

EDIT: Here is a screenshot of the issue. It was taken in the <1s time period that the dialogs were on screen. Also, this issue might be related.

Hi igetgames,

Please provide more information about your Mac’s specs. You can find this in the Apple menu >About This Mac>More Info> Add the information from this window (serial # not necessary).

Also, please provide steps to follow where you can reproduce this consistently. Include what type of project you are in when this happens: ie. Blueprint Third Person Template etc.
