I don't know if this is actually a problem or not but posting it here just to let you know.
I was just on this thread www.mumsnet.com/Talk/relationships/4327659-He-won-t-propose-until-I-lose-weight and I noticed that a post by one poster was highlighted in grey. Not the same colour as I have my posts highlighted (dark grey), nor the same as the OP (dark green) but the same colour as a deletion/withdrawn message, of which there is one above.
This is Not Normal, so thought I'd let you know. Laptop, Chrome, Windows.
