I need your expert advice.

1) My yahoo messenger is not working properly. When i type a message in the lower colum and press enter, i cant view the message in the upper window.

2) I cant use the search criteria. It just shows the animated image.

3) I cant change or create a new user account.

The OS i am using is Windows 2000Xp.

2.8Ghz pentium 4 HT preocessor, 512 MB DDR RAM.

Can someone provide me with a permanent solution.
