Thanks for highlighting this software Graham .I mentioned this a few months ago when I altered a shot in one of the critique forums.I didn't get much response though I find it works very well especially the Vignetting correction as well.
I also use DCE tools "perspective correction" for quick correction.This works very well and in a more simpler way by "pulling" the grid and seeing the result in live preview side by side. It also has the advantage to pull the grids to beyond the edges of the shot.
