I apologize for double posting but I have a few problems

When I click a vertex, the surrounding changes colors and it moves as I adjust that vertex and it really bugs me somehow. (Attachment below)

Also I accidentally pressed the space bar on my work space and it did something and now my top left workspace/view and right are now linked and have the same view. I've tried to change it back to "Top" or "Perspective" but it just changes both of them if I try to change one.
