Nope. That's something only Yahoo's developers can fix, and based on my experience, they really aren't all that interested in user feedback.
Basically, when it comes to dealing with web apps like Yahoo email, you're pretty much entirely at the mercy of whatever the developers of that site provide. As much as anyone else may want to help you, there's really nothing they can do. This is one of the aspects about "the cloud" which is often missing from the general discussion.
In my yahoo mail I get notices from freecycle which is a wanted and offer for free site.The subject line might go like this: OFFER: mens jeans both blue and grey.However with the long subjects when I look at the subject line I can't see it all.I will see something like this:OFFER:mens jeans both.....
I used to be able to see it all just by putting the cursor on the subject line but that doesn't work anymore.It might have been a different computer.Do any of you know if there is a way to get that cursor working again so I don't have to click on the subject then wait for the message to read the whole message?I am using firefox browser.Thank you
