YoungBR,
Have you tried changing compatibility to Win2000 or NT? It's point 5 in the 'fixes for LW' in my earlier post.

ldyj,
When you reinstalled LW, did you use the online or offline installer? Did you update your Java? Did you try deleting the preferences folder? If not, there are links for all of these in my earlier post... give it a try. If nothing works, you could also try changing compatibility.
