Hi, Greg,
Thanks again for your comments. I got it to work with your suggestion:
library(tcltk)
tt <- tktoplevel()
ts <- ttkscrollbar(tt)
tc <- tkcanvas(tt)
tkconfigure(ts, command = function(...) tkyview(tc, ...))
tkconfigure(tc, yscrollcommand = function(...) tkset(ts, ...))
tkpack(tc, side = "left")
tkpack(ts, side = "right", fill = "y")
I think the bug should remain open though, because crashing R is never a
good thing. But for now, it's not on my critical path.
Thanks,
--sundar

I don't know if this is the case here or not, but putting in scrollbars and=
scrolling can be a bit tricky. It usually works best to create the canvas=
without a scroll command, then create the scrollbar(s), then use tkconfig =
to go back and add the scroll command to the canvas after the scrollbar has=
been created and placed.
Hope this helps,
