Thanks for the detailed instructions. I can reproduce this in 2.3.1, and a fairly recent (but not today's) R-patched build. I'm just building a current Alpha build to test it there. I'm not sure it's something we'll be able to fix: tooltips are very complicated things, involving tons of DLLs outside of R. This could be an Adobe bug (since Acrobat might be involved in producing a tooltip for a PDF), a Windows bug, or something completely unrelated that just happens to be hooked into Explorer. The fact that we can both see it suggests it's either in R or Windows, though. > 8) Click "Don't Send" from the dialog > 9) Observe that "Rgui.exe" is now using all available CPU resources for that > thread (this is about 50 for Hyper-threading-enabled or dual-core CPUs).

You can download (approximately) daily builds from cran.r-project.org/bin/windows/base/rtest.html.
