I have not had this problem in a while, but all apps are taking forever to launch again. I have done the usual /etc/hosts modification. I also noticed a lot of odd entries in my messages file:
Sep 30 13:33:12 snowx-desktop -- MARK --
Sep 30 13:53:12 snowx-desktop -- MARK --
Sep 30 14:13:12 snowx-desktop -- MARK --

Sep 30 16:13:12 snowx-desktop -- MARK --
Sep 30 16:33:12 snowx-desktop -- MARK --

For example. Any help would be greatly appreciated.

Thanks,
Mark
