Window Docking - Should it be done by default?

[tkbd]

Before,I felt the same inconvenience as oort did.
but,I thought that is an intentional reason and I didn't post the inconvenience here.

dgud,How about could you make more narrow a response area (transrusent blue area) for decide to docking or not?
Currently the area is too wide and it will be docked immediately in the places.
For example the area for changed after.

   

With this method,you could integrate both user's experience without changing current docking key operation.
It can also place windows when operating Wings3D in full screen mode.
