When creating a new object (tickets, checklists, and everything else), there is an option
called "Milestone" which seems to link this new object with existing milestones.
But whichever milestone I choose, activeCollab does not save that information. Newly created
object simply displays "Unknown Milestone."

I am playing with "limited hosted demo" version using firefox, IE on both Mac and Windows.

Is this a known issue, or does this happen only in the limited demo version?
