UPDATE> Windows Live Writer plug-ins
I have found that a couple of my plug-ins, namely Social Bookmarking and Smiley Plugin don’t work as expected in Windows Live Writer’s latest version. If you are encountering any issues and running Vista machine, please try running WLW as an Administrator.
Apparently a few things changed with WLW and I am still investigating if there is a way to make this work in a Non-Admin mode. I will keep you posted if I discover the root cause.
