trying to click an object

[nate]

I have this icon in a window that when I move my mouse over it it changes shape. and then when I left click on it opens another window.
Ok.. so this command works:

lef 100 100 "window title"

but I cant use it because I need to repeatedly open that window and I need my mouse free to do other stuff.

but 123 "window title" or
but+ 123 "window title" dont work either, dont know why

could you please show me another way to open that window.
something that will work even when "window title" is minimized

thanks a bunch
