how can i avoid switing of alt tag/img src position in docum

hi all,
i am having problem with switching in positions of img alt & src tags.
example :
my page has image tag , initially the code for that is like :
<img src="http://www.example.com/trynow.png" title="try free trial " alt="try free trial"/>

And when i save the pageeven without a change for the first time, the positions of attributes changes & the img tag looks like :
<img alt="try free trial" title="try free trial " src="http://www.example.com/trynow.png"/>

And second time if i save the page even without a single change then the tag is exactly the same as it was originally.

And due to this change in positions of attributes, the comparision result show that the document has been updated which is not the actual case.

So, is there any setting in config of fckeditor which will prevent the switching of attribute positions.
