Hi,
In version 3.0rc6 there is a problem that will open 2 winbox window when using command line:
winbox.exe ip user pass

The request is providing a better winbox command line:
for example:
winbox.exe ip user pass secure session

the window should response the user if user name or password is incorrect.(same as winbox v 2)

This helps automated winbox creation for business.

Regards,

This would be useful to create a "winbox" tool action for monitoring systems.
