Im no pro with Illustrator, but I can work my way through it pretty well. I was working on some type today, and every time I click on an object to place it somewhere,when I get to my destination, the object is shaky. I have to move it back and forth a few times to get it in place. I'll place it where it should be, and it moves just a tiny bit. Not accurately I guess I'm trying to say. It just started happening in the last few weeks and is driving me nuts. Any ideas?
Could be grid snap, or pixel grid alignment. You can try turn off both options.
For grid snap go to View menu and uncheck Snap to Grid.
For pixel grid open the Transform panel, select the object and uncheck Align to pixel grid.
