img and <a> tag attribute position change

hi

when ever i switch between the source and editior area in FCKeditor the attributes position in img and alt tag donot persist i.e the their position donot remain same each time i switch between the 2 areas.
eg: <img class="left" title="abcd" alt="abcd" src="http://images...." /> this occur first time
<img src="http://image..." alt="abcd" title="abcd" class="left" /> next time.

similarly the thing happens in <a> tag.

Thanks.
