I'll try again, below.
But I've just tried a test with a filter as per DaveBC's idea in post 40
ie. regex on
http:\/\/[-a-zA-Z0-9@:%._\+~#=]{1,256}\.blueyonder.co.uk\/[a-zA-Z0-9]+
This filter doesn't catch blueyonder emails.
Here's another go at the screenshot. Seems to have taken this time
Surprise, surprise - Virgin software struggling with a 45k picture? I'll try again.
Oh, no. It shows OK before I hit 'Post' and then it converts it to an link which won't open.
Next try - below should be two pictures - the original, and a 50% reduction. Hope it works.
