Thanks sincerely for the quick reply. Even though I don't really need PE on my powerbook, I tried installing it on the PB and it went smoothly.
I did try to look for anything that the trial version might have installed prior to installing the full PE and nothing obvious appeared. Do you know where I might need to look?
One of the things that *appears* to me to be a nice advantage on the Mac side compared to windows is that (I am fairly new, so maybe I am fooling myself on this) there does not appear to be the tendency to have all kinds of dependency files, libraries and such scattered across all kinds of directories when a program is installed. It appears to all go into one folder. So nothing appeared obvious to me when looking for a previous install. I will look again though!
What is fsck? Thats a new one to me!
p.s. couldnt resist playing with PE on the powerbook. This is one very cool program. It seems very help oriented, compared to what I remember photoshop to be like after being forced to use it one afternoon. This is going to be great for helping me design DVD menus.
