Yes I am also having the same problem in Vista Ultimate. I can erase through the right click menu option, but right clicking on the Recycle Bin to erase it contents always says that the recycle bin is empty even when it is not. Because of the recycle bin issue I have not had the guts to try the Erase free space option which I used in XP fairly often.
I posted another message in the Eraser Suggestions forum suggesting a fully Vista compatible version. There was also another message from kussi in this forum on January 7 mentioning the Recycle Bin problem in Vista Business RTM that was responded to by another user having the same issue. This is a problem that is affecting all Vista users from the looks of it.
The only post I can find by an admin of the forum on the subject was in response to a post by jsmith79 on November 23, 2006 in which he asked if Eraser was going to be compatible with Vista and the admin replied as follows:

Hopefully the post from Garrett means a new version of Eraser that is Vista compatible is on the way. I hope so as I love this program.
