I'll try this and see how I go. I'm on a Mac 10.6.4 I can't give examples of how the flash files look, as they only appear that way when they're uploaded. It looks as though they aren't high enough resolution, so the edges aren't sharp in the graphics that are displayed within the flash files. The header on the site, that is simply a jpeg, looks fine, it's only the graphics that are in the flash files. I haven't experienced the problem when looking at other sites though and I've built numerous flash files on this latest adobe creative suite, as well as previous versions and never had the same problem. Thanks for your help. I'll let you know how I go

I tried what cor-el recommended, loading the page and pressing "Command + shift + R" but it didn't make any difference. Thanks for your reply also the-edmeis
