What are your reasons for blaming Winamp? Have you tried to contact
the developer of the Minilyrics plugin? What version are you using? The
one on the main Winamp site is from 2004!
Have you tried adjusting scroll speed? Look at link below.
If the DX version you listed is correct, it should also be updated. Run the
"dxdiag.exe" app in the "Windows - System32" folder to check. Link below
is to Microsoft's DirectX updater.
Also check your notebook maker's website for any updated drivers for your
notebook's hardware. Do not trust Windows update for hardware drivers.
