I'm using ithe 138.1901 eap and am finding that when I debug php scripts the debugger keeps "losing focus." What I mean is that about four seconds after a breakpoint is triggered, the run and step buttons become greyed out and f8 doesn't work either -- I have to click on the topmost frame and then the buttons become available again (as well as the shortcuts).
"Losing focus" is the best way to describe this, I think.
Has anyone else had this issue? It's happened for the past couple of builds as well. I never noticed it in the stable (non-eap) version.
