I am having yahoo ID. All the things were working properly till I installed the Opera in my computer. Before that, I was using the Firefox and there was no problem with that. Now whenever I try to move my emails to any of the folders then it s showing me message that says, it cannot be moved. Many of the times, it keeps on scrolling down without any reason when the mouse cursor is moved to the list. Can you tell me that what is the problem with this and also tell me that what I should do to solve this problem? Thank you very much in advance for reading and replying to this post.
