Subject: [Rd] using yscrollcommand in tkcanvas crashes R (PR#13231)
Message-ID: <20081030154013.A9635282BEBF@mail.pubhealth.ku.dk>

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,
