I don't know whether this is specific to (my installation
of) SUSE 10.1, or is more general.
With R 2.6.0, I am finding that some widgets made through
the tcltk package are having problems which become evident
through scrollbar activity. An example is demo(tkfaq) --
see below. To reproduce the problem, I do the following:
after the tk window appears, hold down the "scroll-down"
tab at the foot of the window for a few seconds, then
release. If scrolling stops (as it should, if all is
working correctly), do the same thing again. Repeating
this 2 or 3 times usually results in uncontrolled
(unstoppable) scrolling activity; and closing the window
when that happens delivers the errors that appear in the
transcript below.
My R 2.6.0 was built on my own system,
OS: SUSE linux 10.1
tcl: 8.4.12-14
tk: 8.4.12-14
gcc: 4.1.0-25
Since I had not seen this behaviour with previous versions
of R, I did a check with R 2.5.1: a fresh build today of R
2.5.1 on the same system does not appear to have the same
problem.
Any ideas? Is anyone else seeing this behaviour?
