The patch found in the SIS.Patch1.SHK archive brings new features to SIS
as long as Brutal Deluxe's patched version of Tool034 is installed on your
IIgs.  Loading of long cached pages may be quicker and the Save As will now
save any page instead of giving a Toolbox bug dialog box.

You must be a SIS owner and have already installed the Tool034 available from
Brutal Deluxe's web site:
