Geez, has it been a week already since someone asked this question?
Poser 4 has been around since, what, 1999? 2000? So why do people think that they are the first person to have this issue? Why do they post a new message (and get 4-5 answers) when there are TONS of messages about this issue?
Searching on the word "insufficient" turns up the following: (this doesn't count any threads where the person spelled the word "insufficeint").
