I'm new to houdini, I don't know if it's because I pressed some shortcut that i don't know about or what. But right now I can't move the any nodes in houdini.
At first when I tried to drag the node, it'll snap to it's original place while I still holding the mouse. I searched for some solutions, turned off snap to grid, deleted houdini's preset file in document. Nothing changes, and now I can't even drag the node, it's even worse than snap back midair!!!

same problem, it is very hard to move the nodes.
