Right so i installed the new cs4 edition of photoshop yesterday and found becuase of the opengl interface i had loads of brush latency which made it realy tedius to use and made me yern for the good old day (last week) when i was still working with CS2. but lucky for me (and any one else with this problem) adobe have brought out a update that should fix everything and i just thought i'd share the link.

Pip Pip, Cherio and that!
