The only bugs I've found on my DP Miror Door G4 and a new Dual Core iMac (not the silver one last weeks model

) are as follows
InDesign CS3
The view quality doesn't always change when High Quality preview is selected.
When using tables rigth clicking on a row doesn't always bring up the table editing options. Very frusrating.
There's something else I've found too but can't remember it.
I haven't had any printing issues though, we export to PDF then drop the PDFs into hotfolders where our HQ Rips process them from.
