Question Mark?????

How come somtimes when I try to open certain links in websites (like sound links or PDF) I get a question mark inside a blue box, I have flip4mac loaded .... am I missing a plugin I now this is a abit vague but does anyone have any ideas. Thanks

try a different www browser.. sometimes that will fix the issue..

just tried that still didn't work also loaded adobe reader plugin still nothing. The icon that comes up is actually a blue lego block with a white question mark in it if that helps.

Where did you install the plugins? Looks to me like either Safari (or whatever browser you are using) doesn't know where to find them. Or the plugins aren't the correct version.

Sometimes i get same problem
