Hello,
I see this problem in 2.14.1, a recent dev, and 2.15.0 alpha, but not
in an older build.
Start the R windows console and run this code:
plot(1:10);windows();dev.off();points(10:1)
The second set of points does not show up until the window is
minimized and restored.
If the device is replaced with a file-based one (pdf, png) there's no problem.
The problem is caused by events happening asynchronously: the first
device is made active before the second one is closed, and closing the
second one cancels the pending updates. We should be able to get it
fixed before 2.15.0; in the meantime, a workaround is to call
dev.flush(), e.g.
plot(1:10);windows();dev.off();points(10:1);dev.flush()
should be fine.

I see this behaviour on these versions:
R version 2.15.0 alpha (2012-03-13 r58726)
Platform: x86_64-pc-mingw32/x64 (64-bit)
R Under development (unstable) (2012-02-28 r58513)
Platform: x86_64-pc-mingw32/x64 (64-bit)
R version 2.14.1 (2011-12-22)
Platform: x86_64-pc-mingw32/x64 (64-bit)
I have an old beta install of 2.13.2 where the problem does not occur:
R version 2.13.2 beta (2011-09-22 r57035)
Platform: x86_64-pc-mingw32/x64 (64-bit)
Cheers, Mike.
