Pet Flash Bug #1: No arrow key movement of individual points in grouped objects, sometimes!

One of my biggest gripes with the Flash Professional Sub-selection (the white arrow) tool, is that when selecting points within an grouped object, your arrow keys will lose focus, making it impossible to move these points precisely. What makes it even more frustrating is this only happens sometimes. Most of the times when you have spent a long time selecting points, and almost never when trying to demonstrate the problem to other Flash designers who said they have never experienced it. I'm only griping about this because everyone else seems to just ignore and accept it... this bug has been in at least 2 generations of Flash Professional... I will hunt for a bug report on this... so I can let this pet bug go, or at least find a name for it!
