Vertices not aligning I don't know how this is happening, but I just create a shape, scale it and then the vertices are not aligning. Any help is appreciate.
Here is an step by step process and a link to the video of it:

Create cube
Make it multiresolution
Scale it
Zoom view to sides and front
See the vertices not aligning
Get frustrated

Select the following options: Increment, Scale. It doesn't matter if you have selected Move and/or Rotate:


Click the magnet to activate snapping, hot-key = Shift + Tab. I don't have a picture for this, if you need it you can tell me. Instead of clicking the magnet, you can also hold Control while scaling.
