ScapX notebook will no longer save changes

Since I migrated to OS X 10.6 that nifty scrapbook or notebook with all those neat bells and whistles no longer seems to work except to open but I can't make any changes and save those. It refuses to save giving an error message that saving is not possible. I assume it's because it was a 2003-2004 software (by Aqueous Software, LLC) which also no longer appears to exist. Can anyone help me on this? Is there another similar software available for the Mac? I loved this notebook!
