Yes. Just did it again to verify. I have both my Layers window and Properties window docked to the side of my screen, one over the other. For the sake of demonstration, highlight any dimension, then expand all the dim properties sub-menus by clicking on their arrows in the properties window (> Dimension Lines, > Arrows, > Length Units, etc.) .
The mouse scroll wheel will scroll the Dimensions menu as long as the cursor is somewhere over it. If your cursor happens to be near the right side of this menu then the value fields will pass by underneath your cursor as you scroll. The moment a field is under the cursor, the window continues to scroll but it is also changing the value in the field as it passes underneath your cursor. So the scroll wheel is doing two things at once; scrolling the window and changing the values.
You will see the Title of the values turn blue to indicate they have been changed, but if you’re not looking for or expecting that behavior, you will have no way of knowing that anything just got changed.
This has caused some very costly mistakes in our manufacturing, and drove me nuts until I learned what the source of the dimension errors were. As a precaution now I will do a SelDim and check the Length Factors globally to be sure they are all set to 1.
