can someone tell me what's going on?  i save an assembly, and the * goes away fro about .00001 second, then it is back again.  as soon as i bring the assembly up, it shows the *, even though i haven't done anything but open it.

is this because i have some incontext models, or what? 

SW2009 is very frustrating.  it seems all i do is restart (after it crashes),, redo my work which i lost  (unless i want to do a command, save, do a command, save, etc), and then $%&k arounds with problems like this....
