Hello all!

On the new work there is a milling machine with mach3 programme.
I had only 2 chances to work with classic mach 3, but this looks different a bit.
The main window looks exactly like this:



Please tell me how to open a window where I can change tools (i mean, in the right top corner there should be an image of all my sockets with tools)
And I will be really thankful if somebody would tell me what version is this, because I can't find neither tutorial, nor info about it.
