In this connection also
this post refers (which perhaps better shows what exactly happen
ed (past)), but as far as I know this has meanwhile been solved. (News-section re build 815: "fixed some bugs in skin engine"), in which case there's no need whatsoever to go back to build 806 to create the rgn.dat and rgnfs.dat files (which were
not included in the Media SUBlime skin which I downloaded by the way).
I'm presently using build 817 (builds 815/816 unfortunately were not suited to be used under Win9x/Me).
What build are you using
kylek?
