[Qt-creator] Alerts and dialogs pop up in the wrong monitor in dual monitor setup.

[Stephen Chu]

I am using a MacBook Pro with an external monitor placed to the left of 
the notebook. The external one is my main display with menu bar on it.

Creator runs and places itself on the external one which is correct. But 
whenever an alert or dialog comes up, it's always placed on the build-in 
display. I can drag it back to the main one but it will pop back up to 
the build-in one next time it shows up.

My guess the external monitor, although being the main one, has global 
coordinates in the negatives. The dialog probably has some code protects 
against showing up outside of displays by making sure no negative frame 
locations.

Is this a known issue? And is this Qt or Creator issue?
