Embedded Google Document in IFRAME sometimes doesn't load
<p>I have a very frustrating problem with Google viewer, which is displaying a PDF that is embedded within an IFFRAME on my website.</p>

<p>The really strange thing is, that very occasionally the content does not load and the part of the screen where the IFRAME should be displayed is just blank. If I then hit the refresh button within my browser, the content displays just fine! Sometimes I can view the page 10 or 20 times before getting a blank screen.</p>

<p>Has anyone experienced anything similar in the past, and are there any suggestions for a remedy?</p>

<p>Many thanks and best regards.</p>
