Cannot resize / move an image (sometimes)

[wizzlybet]

I have an image I have added to multiple pdf documents.  However, sometimes when I add the image (a jpg) it inserts but I cannot resize nor move it.  I have to delete it.

In other documents the same image has inserted and then been able to be moved and resized as expected.

When it fails, the mouse cursor changes shape as I hover over corners/edges but nothing happens when I click to drag.

Any ideas what is happening.  At present I am wasting so much time and end up using another pdf editor.

What application are you using, exactly? Because none of this is not possible in the free Adobe Reader.
