Windows TempFile permission denied

[Robert Evans]

Hi,

I looked for an answer to this problem, but couldn't find one.
Running on Windows with 1.8.3, I use the TempFile library to create a
temporary file, but I get a permission denied message when I try to
do that. It doesn't happen all the time though and it works fine on
Linux and Windows.

This also happens running rails on windows occasionally. Anyone know
what the problem is and more importantly how to fix it?

Thanks,
Bob Evans
