Thanks John - that now lets me at the menus properly.

Re the problem of showing some photos "wrong" - I should have been more 
clear. It's not your problem - it's (I think) a bug in Rev's handling of 
scaled images - it gets certain images wrong whenever it scales them. 
Most images show correctly in all three of the "open" variations in your 
stack.

But certain photos don't; they show correctly when I use "open without 
scaling" - but both other versions of open (and my own viewer) get these 
photos horribly wrong. The left portion of the photo is correct - but 
then it starts to get streaky, and by the time you get to the right of 
the photo, it is showing only streaks.

You can download a sample "bad" photo from www.tweedly.net/IMGP0635.JPG 
  - but beware it's 1.5Mb
(btw - it shows a crowd of us from the EuroRevCon 2004 in beautiful 
Malta !!)

This photo looks fine in Windows viewer, and in Photoshop, and in ..... 
and unscaled in Rev, but not when scaled.

I have only seen this problem on large photos - my camera produces 
3000x2000 pixels - though I haven't yet experimented much; until today I 
had assumed *I* was doing something wrong :-)
