Why am I not able to open my yahoo mail on my laptop?

Why do I experience these particular problems with Yahoo Mail on my laptop?

• I've got a toshiba satellite (L300-1AQ) laptop. Recently, I began to experience terrible problems with my yahoo mail: 1- When I click on an unread email to read it, I only get a compose new message page...When I click check mail, I find this email marked as read. 2- Frequently, after I finish composing a new email and click on SEND, the screen displays a blank message that need to be composed...When I check the SENT folder, I find out that the message was sent...But the problem is that I needed the automatic yahoo mail option of saving a new contact after sending an email to a new recepient (which I no longer find). 3- Other similar problems all of which revolve around displaying a blank email that needs to be composed without clicking on COMPOSE. What's particular about this is that I discovered that this always happens ONLY when I access my yahoo mail from my toshiba satellite laptop (mentioned above). It sounds like a web-based problem, but why happening with my laptop only? Are there any mates experiencing the same (or similar) poblems with Yahoo Mail...Hope that anyone can help me understand this and sort it out! Thanks so much in advance!

• Answer:

  Sign out of Yahoo. Then delete your temporary Internet files, history and cookies, some computers need to reboot. Once done, go back into Yahoo and see if that has helped. It might be a good idea to clean out any unnecessary data from your computer, delete Internet temporary files, history, cookies, saved passwords, and web information, plus any duplicate files. Store any added data on a USB drive, Zip drive, CD, or DVD. After that, do the maintenance on your computer: 1- Disk clean, 2- Check disk, 3- Disk defragmenter. If you have a registry cleaner, use it. This should help to give you some space back and get your computer in better shape and working faster. Do it regularly to help to keep it that way. Hope this helps.
