Hi there - I���ve been running in a 6.1 64bit image for a few days - doing a few experiments at lunch times, debugging things etc. I have had a few infinite loops that I���ve had to Cmd-. Out of�� and clean up lots of windows (whoever came up with the close all windows to right is a star!).

Anyway, I just noticed that now when I drag windows around in the world - they leave lots of window trails around. Redrawing the screen cleans it up - but I���m wondering what causes this?
