Focus is not on Python editor when opened


Is it only me who is experiencing this issue?
When I open a Python editor by double clicking GHPython component (Rhino 6, Windows 7, 64bit), the focus is not set on the editor but on Grasshopper. Even more, when I click the editor once, the focus is still not on the editor but on Rhino.
So, this is making a lot of problems like pasted codes go in to Command line of Rhino or I mistakenly select all the compoennts on the GH Canvas.
Does anybody know how to fix this problem?
THank you.
