Why is my yahoo mail, delete etc. buttons, covered up by search mail?

Pushing F11 will restore the menu bar. Maybe it will work to restore all your other stuff in Yahoo Mail, too. I don't think that's going to work, though, because that's not in your browser's menu bar.

Btw, I found out about F11 by searching the archives & resolved questions in computers. Maybe you could search Resolved Questions in Yahoo! Mail. Also, I'll give your question a star in case one of my contacts knows the answer.

One contact of mine says it MIGHT work to clear cache, cookies, & temporary files & to try exiting your browser or even doing a complete shutdown of your computer. Sometimes doing these things will remedy whatever ails you. Can go to History in the menu bar & then select Clear Recent History, clearing all. I've done that many times or everything except cookies. Sometimes it needs it done weekly if I've been overly active.

This happens to me all the time. all you need to do is click on the 'Refresh' (Arrow shaped like the letter 'C') This will clear your problem
