I selected a number of objects which included some rectangles and some circles. After selection, I rotated the entire selection +90 degrees and also moved it a bit sideways. After rotation, trying to change the diameter of a hole results in strange results. For example, a hole was 0.250" both height and width. After changing the width to 0.150, the height changed to 0.750 on its own. Then trying to change the height to 0.150, makes the width 0.030" and the height stays at 0.750".
Rotating by -90 degrees, restores normal behavior.
