Preview: Folders containing .eml and .nws files

Using WDS 02.06.6000.5414 on XPProSP2, I found that preview did not work for
some .eml and .nws files. The only common factor I could find for the ones
which would not preview was that they resided in a folder whose path included
an apostrophe ('). I have not checked whether other file types are affected
in the same way.

Could it be that the template use for displaying these types of file
includes a line something like src='C:\%path%\%filename%', which of course
would fail if %path% (or indeed %filename%, for that matter) included an
apostrophe? If so, is there any way of changing it, for example to
src="C:\%path%\%filename%"?

[I tried posting this in the Windows Desktop Search Help forum, but no-one
has responded as yet.]
