A small bug was causing some stats not to update properly. This is now fixed (Version 1.1). Please redownload.

Also, with regard to making stats stay on the screen:
I considered this but I didn't know if it would be appropriate since it really is a chat log primarily, and all stats it generates are based on the log. (Therefore if an event occurs that is not recorded it might mess up the integrity of the stats). Also, it might look ugly to cram lots of extra stuff into the main window. I was also considering however making a seperate program (SaLStatS) which would generate stats in real time and be much more detailed and accurate. I might make a quick version of it soon.
