Trying to Zoom in and out while a dimension is selected and the value is changing.
Solution
This will happen if the following Option is enabled:
Application button -> Settings -> Options, General page -> Enable value changes using the mouse wheel.
While the mouse is over the dimension value box, the value will change, but as soon as you move out of the box, the Zoom function will be enabled. Uncheck this option and it will only zoom.
