Comment on Mac os X LynX for Windows 10 rtm by ZEUSosX

There is no way to control that, from what I know, specially if we want to have borders to windows (this is a native windows 10 construction, and one of the reasons that native Aero has no borders, as also the slight vertical line near the edges of titlebar)
The 'solution' of microsoft, is not to make better and more accurate and symmetric the system, but to make a noborder and 'flat' theme like win 10 Aero which hide those constructive faults.
