No, it isn’t an option at the bottom of the left column of topics anymore.
Yahoo has changed their page slightly again. Now, quickview is turned off. Quickview is the feature that lets you open up your mail and so forth by rolling over the topics in the topic column.
It used to have an option on the bottom of that column called “turn on quick view on rollover”.
Yesterday, that option disappeared and I can’t preview my mail or anything else without clicking on them. It’s annoying.
Anyone else notice this? Is there a new way to fix it?
Most google searches give me the old way to do it. 
I wonder if this feature was just too heavy on their servers and/or was crashing a bit too much due to heavy HTML content in emails, and they simply discontinued it.
Depending on how they do it, they would have to load the contents of each email into memory when the page loads, and it may have not been executed properly and was slowing the system down. It also could have been a security leak to allow spam/malicious emails to open in that manner. One of those things that was a good idea and useful, but not practical at their level.
I don’t use Yahoo but when I open it I see lots of quickview junk on the left side.
If you click Logout/Sign Out, does it look normal again? I’m wondering if the settings are saved as part of your yahoo login or are something remembered in your browser?
If it’s your browser, my suggestion is to clear your cookies for yahoo.com and see if it resets your settings. If you’re worried about your cookies, you can first try opening yahoo on another computer or another login on your computer if you have such capability, to see if the “default” settings match what you’re looking for.
Anyway it gives you something to try.
After reading the last response I retract my suggestions as it looks like it’s not going to be cookies.
You used to be able to do so from the settings, and it’s still listed in the help page, but that setting is no longer available. It’s pissing me off too.
Morons. I can’t believe they deleted this option.
