Answer 1

to fix an that app's perms usually this works:
sudo chmod -R =rw,+X /Applications/VirtueDesktops.app
or
sudo chmod -R =rw,+X,g=u /Applications/VirtueDesktops.app
a. This returns all files in the app to their usual UNIX defaults.
b. Some apps will require r/w permissions on the group to function.
c. All OS X apps should bear admin (80) as the group ID
d. Some apps require owner be set same as user, most like owner set as root.
Snow Leopard's Sudo visiblepw flag is no longer set as it was in 10.5.x
The "visiblepw" option must be entered into the Defaults
section of the /private/etc/sudoers file in order to allow
sudo to run in 10.6 when a tty is not allocated. From the
sudoers manual:
"visiblepw
By default, sudo will refuse to run if the user must enter a password but it is not possible to disable echo on the terminal. If the visiblepw flag is set, sudo will prompt for a password even when it would be visible on the screen. This makes it possible to run things like "rsh somehost sudo ls" since rsh(1) does not allocate a tty. This flag is off by default."
Using visudo, Add the line "Defaults visiblepw" to the Defaults section of the /private/etc/sudoers file and the following error message will no
longer appear:
sudo: no tty present and no askpass program specified
A valid workaround is to use the
"-S" (capital S) option with sudo.
I noticed you used su with sudo, that is not cool.
