system(wait = FALSE) seems to fail

Thu, Jan 13, 2011 6:11 PM

I'm having problems with system(wait = FALSE) with R 2.12.1 (both i386
and x64 versions) on a 64-bit Windows 7 machine.

This is as expected:
print(system("cmd /c dir", wait = TRUE))

This fails:
print(system("cmd /c dir", wait = FALSE))

I did not see this with 2.12.0, and things seem to work fine with R
2.12.1 on a 32-bit XP machine.  Can anybody else confirm what I'm
seeing here?
