Rails spinoffs - Jun 2006 - Very cool scriptaculous table drag and drop stopped working on new version

Using older versions of prototype.js (1.4.0_rc2) and scriptaculous 
(1.5._rc4), I had a master table containg other tables (sections), each 
of which had rows.  Using tbody''s as containers, I could drag the 
section tables up and down over the other section tables AND drag the 
rows in a section table up and down within that table or into the rows 
of the other section tables, all very cool.

I want to upgrade to the current scriptaculous/protptype combo (for 
window scrolling), but when I do, major problems appear.  Now when a 
section heading (section table thead row) is clicked and the cursor 
moved, a highlighted select is performed instead of a drag.  And now 
when a section table tbody row is clicked, it generates an 
"Element.Class has no properties" error and the dragged row cannot be 
dropped.

I''ve attached a zip file, OldVersionTest.zip, which unzips into a 
"OldVersionTest'' directory which contains the old versions of
prototype
(in /lib) and the two required old scriptaculous js files (dragdrop.js 
and effects.js in /src) and a test page, DEF_Test.html in the /test 
sub-directory.  Open DEF_Test.html (only tested in Firefox and IE) and 
it works perfectly (in Firefox, the move cursor doesn''t show when 
hovering over a draggable section or section row).

If you copy DEF_Test.html into the test sub-directory created when 
scriptaculous.js.1.6.1.zip is unzipped and open it there, the problems 
will be apparent.

Any ideas, anyone?

Thanks
