Can't get Default email client to stick

[eichlerguy]

Hi, all,

I have Entourage on my machine but want to use Apple Mail as my
default mail client. Despite having set Mail at the OS level,
Quicksilver continues to believe that Entourage is my one-and-only
mail client. And choose 'Default' in QS preferences doesn't stick.

Any ideas?

Thanks.
