In short: Microsoft Office 2007 - Groove aplication creates a conflict with Photoshop CS3. just uninstall Groove and off you go, all is working perfectly.
Hope that helps.

Answer 1

Thanks for the replies.
I understand now that the procedure is probably the reason.
I was just experimenting as LAB colours are colours we see through our eyes, while RGB, CMYK etc are "computer" colours and so I use LAB colours a lot, before switching back to RGB.
I normally switch to LAB mode and click on the Lightness channel, then play with adjustments of that channel. This time I decided to mess around and see what would happen if I removed all channels except the Lightness one....
Converting to greyscale for me is not enough unfortunately and LAB B+W provides much better contrast and tone than hitting CTRL+Shift+U to greyscale.
Again, I understand what you say, my point being though that Photoshop should not crash because I incorrectly remove the channels, perhaps a warning to tell me I can't do it would be better.
I'll pass this onto Adobe anyway.
