If you are using IM9 it has a lot of bugs. I downloaded IM8 because IM9 had so many problems.

If you need to download older version go here

just click

alt+ctrl+delete

then

a box will show up find "explorer.exe" and select it then click End process

now your taskbar will be hide, again click alt+ctrl+delete then again that box will show up after that go to your menu click file and click "New Task"

a small box will appear and write there "Explorer.exe" and click ok

your taskbar and icons will show up then open yahoo it will work
