When setting a breakpoint in an event in a BP while playing in editor, I often have the mouse cursor trapped inside the editor window. I have the map I play in one window, then when the break is hit, the blueprint is brought up in another window, the editable area is shown with a yellow frame and the cursor is trapped so that I cant rech the resume or any other button outside the area. I have to hit the “window” key on my keyboard to bring up the windows start menu in order to free the cursor. When I go back into UE I am then able to click the buttons all over the screen.
I do not think this happened in pre 4.12 versions but I am not sure. All I know is that it happens nearly regularly now
this is just another workaround, but does shift+F1 release the cursor?
Nope, I have to leave the UE environment to windows to free the cursor
Hello ,
I was able to reproduce this issue on our end. I have written up a report and I have submitted it to the developers for further consideration. I have also provided a link to the public tracker. Please feel free to use the link provided for future updates.

Make it a great day
Can confirm this is still occurring in 5.3.2
Completely breaks workflow and makes live debug very difficult. Issue appears to have been closed as WONTFIX

The problem is still with us in 5.4, too. I cast my vote on the ticket.
