Hi Tanya,
Sorry I should have updated this post sooner - I seem to have resolved the Chrome issue - I needed to save my comparison image as PNG rather than JPG. I'm no graphics expert, but seemingly something in how JPG's are encoded and PNG differs - I was capturing the JPG from IE, which resulted in a match, but something in how the two browsers render things is subtly different, but PNG somehow "resolves" this.
Don't ask me why, but touch wood it seems to work!
That said, the issue with PagePicture and IE remains - when TC captures the "additional" bits of the screen to append to the overall image, it appears to capture a row of 1-2 pixels in height at the bottom of the tab bar. Can you advise here?
Thanks again
Steve
