SPSS (PASW) 18 bug

SPSS seems to be a very hand application. Great, just button click your way through your stats, this is very good. Well, the application is a little unstable though! I think it's written in Java (which isn't a bad thing). Using my data set, which is fairly large with 608 thousand data points, I would like to copy and paste a column of data from one sheet to another. In Excel this is a fairly lengthy operation, it takes in the region of 4 mins. I did this in SPSS also and it has now been running for somewhere in the region of 18 hours. This is using a full CPU core, so there must be some number crunching going on there!

Let's hope this get's fixed in the next release. If someone were to wish to debug it this has been tested on a Windows 7 computer, based on an Intel 4 core processor. It's also been replicated on a Windows 7 Intel Atom based netbook.
