"Page not found" on Drupal 4.7

Hi,

Apologies for a double post - seems this would have been the right place to ask!

Have tried both the 4.7 and the CVS release of this module and am having problems. When enabled, all the links appear fine in the correct places, but when a user clicks on the "Email this page" link they get "Page not found" on every one.

The web browser (Firefox or IE) shows that they have tried to go to the address

www.example.com/?q=emailpage%26nid%3D31

for instance, and this is how it is shown in the source - i.e. %26 instead of & and %3D instead of =

I wonder if it is anything to do with cleanurls? I do not have them enabled. I've examined the settings and searched for assistance but can't see what I'm doing wrong!

I also figured it might be something to do with line 51; I changed the reference there from
"emailpage&nid=$node->nid"
to
url('emailpage', 'nid='. $node->nid)

but it didn't help (it didn't make it worse either!). Didn't surprise me much, because I am extremely amateur and it was basically the trial and error principle :-)

Thanks for any help. I am guessing I'm doing something stupid as I can't find anyone else having the same problem!
