You´re right, Terrapin
it did made a huge difference.
The 7zip filesize is now ~25MB compared to ~33MB with rar format.
i used the default settings, just changed the compression level to "ultra"
Maybe there´s even more to shrink
Of course i´ll release the next version in 7zip format, but i dicided
to keep that 09122005 version as it is to avoid confusion
(one file is already updated in the 7zip version)
