Bad bug in the Windows Client? (Case issue - duplicate files)

I have encountered a severe problem with subversion in windowsXP.

I believe a user copied over a file called temp.JPG that they wanted to
add to subversion, however another file, temp.jpg already existed.
Windows overwrote the old one, subversion thought it was a new file and
allowed the user to add it. Once the file was committed,

It appears that users can commit files with the same names in different
"cases". Linux handles this just fine, but windowsXP does not. Currently
any user that tries to checkout from the repository in windows will get
an error and cannot proceed. Even once I fix this, around 2 dozen
revisions will already be "un-checkout-able" for them.

Shouldn't subversion have the ability to prevent this?
Does it already?
Do I need to create a hook?

I need a way to prevent hundreds of users from doing this, many of which
are not computer literate. Any ideas?

Some old references.
