The problem is sometimes the actual value of object size and position not the same as what they're being setted.
e.g. select "Size and Position" in the right-click menu of the text object.do nothing and press "OK" button. then strangely the text object is moved. select "Size and Position" in the right-click menu again, then found that the X,Y,Width and Height value are changed !
It makes me a huge effort to set the text objet size and position since such strange behavior.
Is it a bug or a feature ?
