When I last looked at this problem on my own forums, I found that basically the onload action was not firing properly in the <iframe> (in the template file include_post_html_common_write.html). Here is what I did, and it seems to have fixed it... because there have been no more complaints :)
My fix was to simply move the onload function call in the <iframe> tag up into the onload function call in the window.
So, delete (or comment out) "onload=initOuterIFrame()" in the template file "include_post_html_common_write.html".
In the template file "edit.js", add the following line "window.onload=initOuterIFrame;". Just insert this line below the "window.onresize"... but it doesn't really matter where you put it.
Try to see if you can duplicate the problem on my forums, and if it doesn't happen... then this fix should probably work.
