Hi, This is my first post and i´m fairly new to apple so please be gentle! I have recently upgraded from 10.4 to 10.5, everything has been fine apart from i now can not seem to be able to download anything. When i click on a link to download, the page loads for a second and then gets stuck on a grey screen and the download window doesn´t open. I have tried different browsers and all of my updates are current but still nothing. Please help, any advise will be greatly appreciated.
