Error: unknown option "-padx" while executing "frame $w.scrolled
-highlightt 0 -padx 0 -pady 0". After removing the "-pad...", It works fine.

So I changed the "pack" to "grid" about 4 items into each row. I then
tried to loop up to 5000 times adding rows to the frame. It crapped out
at 2482 lines, the exact same problem I had with my original code when I
was using a canvas.

Running it on Linux with KDE, the window just got garbled and couldn't
be scrolled. On AIX using an Xwin32 emulator to my PC, it failed with an
error out of memory, and on windows 2000 it left the window blank and
put all the widgets in the upper left corner of the screen then locked
up. In every case I had to kill the processes.

So I guess my question remains the same - How to I scroll a large list
of widgets gridded onto either a frame or a canvas?
