Ok, I don't know who decided to only allow docked tables in this version, but it was a HORRIBLE decision. You have people so used to being able to move tables around, minimize, etc...(which is a core component we all have to use) and then you don't allow use to do anything but tile windows to a docked window!! That is a horrible solution and the software needs to address this in the next version to go back to the old way of windows structure. Let the user decide where to place tables, not the software!
This idea has been merged with Allow attribute table tab to open in a new window in ArcGIS 10.
