You can't "minimize" the window but you can drag it out of the way,...mostly. Then you can get at the windows side of the control.
You shouldn't have to drag it out of the way.....
If you use the mouse pad and move the cursor all the way to the bottom of the screen(to the point where you can't see the arrow anymore), the windows task/start bar should show up. If not, try left clicking in the bottom area and the bar should show up. It's set to be hidden....
It's just a part..... cutter still goes round and round....
