I am using Blender 2.49
Ok, before yesterday the cursor would automatically snap to whatever I select. Now, every time I select something (e.g. a group of vertices), the cursor does not snap to the selection. I believe I pressed some key that altered the automatic snapping. I know you can press SHIFT-S to do it manually, but doing that is extremely annoying and time-consuming since this particular model I am working on has a lot of vertices. I would like the cursor to go back to automatically snapping to my selection - any help with this problem is greatly appreciated.
