Hi Luke,
Firstly, thanks for the software.
I have been experiencing what I believe is an AOO error. This kind of error comes up in AOO 3.x and 4.0.1.
In AOO 3.x, the following is the error:
The error in 4.0.1 is a bit different, but pretty much related to some AOO package, along the lines of java.sun.com/XXX/XXX etc.
I think I have installed the complete AOO package (137 MB download).
