Infinite loop in image conversion

I have downloaded and am evaluating the trial version of RoboHelp 8.  I started a new project, imported an existing Word document, and tried converting it to WebHelp.  It processed the document and converted all the images to bitmaps, and then came back to one image (the tenth) and started an infinite loop creating additional copies of the image.  I tried deleting that image in the Word document and creating a new project, but it did the same thing again, this time starting an infinite loop creating additional copies of the ninth image.  Has this behavior been observed before?  Is there a fix?

Thanks,
