Photoshop problem when using space bar as Move tool when using the Lasso tool

Having this problem after I change a new computer with Windows10. I am using Photoshop CS6.

When I zoomed in on an image and making a selection with polygonal lasso tool, I used to be able to hold the space bar to move the image around. Once space bar was released, it would revert back to the lasso tool and retain what I had selected, allowing me to continue selecting. Now, if I press the space bar during a selection, it doesn't switch to the hand tool and allow me to move at all. The polygonal lasso tool remains and I cannot shift the image around.

this problem happened on both polygonal and magnetic lasso tool.

I am not using pen or Wacom tablet, just using computer with mouse.
