Going through emails to delete some. Every few deletes pops a "click save for later" which moves the entire page UP about 2 inches. This moves a new email under the mouse and as I click the trashcan you force me to delete an email that was NOT my target for deletion.
This is BAD FORM on the internet. Once the page has "settled" the contents should never be moved except by user interaction. This is actually bad enough to make me stop using yahoo email and migrate all my various contacts another provider. this is NOT good marketing, or "good way to make the user see what we have popped" it is only ever annoying and the developer who thought it was a good idea should be smothered in damp moose hair and paraded down the local interstate for an hour.
