Hi
I am using GDE 2.2.3
I haver a valid (full path) link to a 1 Mb .pdf file and I did notice it was not being viewed until I set Force=1
<!-- GDE EMBED ERROR: retrieve error (0:), use force="1" to bypass this check -->
I have tried fiddling with a few options but nothing as shown me what is causing this behaviour.
