launching Adobe Reader from wxHTMLwindow

[Greg]

I have some html code that is displayed on a wxHTMLwindow in a Python
application.  One of the ahref links is to a pdf document.  When I
click the link, I get what appears to be some sort of header material
for a pdf document, but Adobe Reader doesn't start.  Is there a
special call I will have to use in the HTML code instead of ahref to
get Reader to launch?
