When I selected LW dmg and went to file get info, it did say open with DiskimageMounter (default). The change all was grayed out.
I did do a safe boot and repair permissions last night. I have downloaded a new dmg of LW. I dragged it into disk utility left side window clicked file open and got this message. " Unable to attach "LimewireOSX.dmg" - not recognized. Just as I did before.
By the way. When I come to this page without logging in I can see the links. As soon as I log in the links go and I can't click on them. As I said I get a blue box with a ? in the middle of it.
I went to disk utility preferences and I have checked

Verify checksums
skip on remote volumes
auto-open read-only disk images.

Thanks for you help
