No. This problem has not been reported AFAIK so it must be something
specific to your situation. When you say "color" the event how are you doing
this? Are you assigning a category to the event? If not, add the category
and set color there.

Steps to help determine where the problem is located.

1) you can eliminate your Identity by creating a new Identity in Entourage
and see if you experience the same problem.

2) if a new Identity still exhibits the same issues, then create a new User
in System Preferences and test Entourage there.

2a) If the problem is in your User's account, then log out/in with Shift key
down to disable any startup items. Test. If the problem still exists, it's
most likely a preference file that's corrupt. See  these pages for help:

2b) If the problems still exist in the new User, it's a problem with your
base OS files. If running the Apple combo does not fix, then you might need
to do an "Archive & Install".

3) The last option would be something on the server is locked keeping you
from making changes.
