A weird problem.
One of my users sometimes can't open a pdf doc over the browser and gets a small window with a blue question mark and an OK button, no mention of errors on it but no doc displayed.
This is IE8 trying to display a pdf doc, but sometimes it does work and displays it, like after clearing all cache off IE, not always though.
Can anybody help me resolve this?
