I did not buy in from the Stardock Central window as it
did not have the security lock icon. I used IE to get to
the Stardock website to buy online.
A further point is that now, after reinstalling WindowBlinds,
I can no longer skin the left hand side of the XP windows, eg the
shut down one. I could before! I suppose this is a skinning
problem but I recall it was so on the shareware version (?).
