It is a bug in v350 code and it seems the actual development build v351 fixes the problem. I've just sent it to you by email to test on your side.
A temporal v350 workaroung for the problem is to absolutely position not the image, but its enclosing DIV:
<div style="position:absolute;left:395pt;top:37pt">
<img src="TSTB_images/img-gen6.png"/>
</div>
