In Movie Studio Platinum 14, I could insert a Pan/Crop event at the beginning of a video, set "Maintain aspect ratio" to "No" and then enter arbitrary width and height values under "Position" or drag the individual sides  of the video to deform it.  However, in Movie Studio Platinum 15, setting "Maintain aspect ratio" to "No" has no effect on entering arbitrary Width/Height numbers nor on dragging any of the sides--the aspect ratio is always maintained (for example, entering a new Width value automatically changes the Height to maintain the aspect ratio).  If I Ctrl-click on a side, I can deform the video but I can't do so with the precision of entering a number directly.

Am I doing something wrong or is this a bug?
