just upgraded to CS4
 

Hi All just upgraded to CS4 all seems great just a couple of things though, on opening a RAW image in the top right had corner an exclamation mark in a yellow triange appears for three of four seconds.
The other is you dont have the undo redo arrows that you have in CS2 does anyone know a short cut to get them back rather than keep going edit step backward or forward.
many thanks

[Ctrl]+[Shift]+[Z] is "step backwards" in CS3 and might be the same in CS4.

The yellow "!" warning triangle tells you that the preview image you're seeing isn't fully rendered but is just a lower resolution preview. It disappears once it's properly rendered.

Hi Chris
thanks for that
