Is it possible to make all URL's both permanently active & blue before I email it?
In my opinion the short answer is no.
There doesn't appear to be any way you can guarantee that every link you type into an email composed on Yahoo are always 'clickable', 'live' links/url's, a) because it appears to be the default of the new Yahoo Mail system
not to automatically format links/url's rich text mode and b) because not all of your recipients will have their own email service set to receive emails in html format.
I've used Yahoo mail for years & Win8 for 11 mos.....these quirks popped up in the last 3+mos. Is there incompatibility between Win8 & Yahoo that I can fix?
I'd be more inclined to believe that the problem seems to be with Windows 8 and if you use it, Internet Explorer, as opposed to Yahoo Mail itself as a lot of people recently are even having problems using their Hotmail / Outlook email on Internet Explorer. Microsoft don't seem to be doing themselves any favours.
As a side note, something else I've noticed is that Yahoo has become extremely slow in sending emails. Maybe it's time to switch?

Strange?!
I just composed 1 email in Rich Text and 1 in Plain Text on Yahoo web mail, both containing a link beginning with 'http://' and sent them to the same non-Yahoo address.
The email composed in Rich Text arrived with the link not-clickable - so
not 'live'.
The email composed in Plain Text arrived with the link clickable - so 'live'.
So it seems:
1. The addition of 'http://' before any link (whether preceded by 'www.' or not)
is important.
2. Composing a message in Plain Text and using the above (1.) has a higher chance of the link being automatically parsed by the Yahoo system as a 'live', clickable link - AS LONG AS THE RECIPIENT IS VIEWING THEIR EMAILS IN HTML
Hope this helps.
