HI,
Safari add-ons can cause performance issues or other situations
Also, if you are running Safari in 64 bit mode, try running in 32-bit mode instead. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Quit Safari then relaunch.
And in the Safari Get Info window make sure Safari is NOT running in Rosetta.
If none of the above helps, Quit Safari.
Then locate this file.
com.apple.Safari.plist
Move that file to the Desktop and launch Safari. If you a download files without a problem, then there's a corrupted file somewhere in your Safari preferences. Move that .plist file to the Trash.
Another thing to try is logging in using another user account and see if you can download from Safari there. If you can, the the problem is isolated to just your user account and system wide.
Could you please update your forum profile to 10.6 please... thanks! Click My Settings on the right side of this window.
You could try downloading and installing the 10.6.2 combo update available here. One of the "fixes" includes: *-- an issue that prevented opening files downloaded from the Internet*
