the backcolor of ntop look odd in Powershell

[tlsalex]

I work in powershell much more than in cmd enviroment .

When runs ntop in powershell ,the color or the Backcolor looks odd in powershell , but work well in cmd.

It seems work well if you run the ntop.exe only within powershell , but when you try the option like ntop.exe -h , you will see the problem. see bellow image for more detail
