iNotes as default email client does not work!

I’ve configure iNotes as default email client (via preferences-other) but when I go to explorer and I click on one file and then I rightclick and click on “Send to recipients”, the webmail main Welcome page is shown but no memo is created. If I click on a “mailto:” link, nothing happens…

Is it normal?

I confirm that C:\WINNT\DOWNLO~1\inotes6W.dll is well installed and registered… and that in HKLM/SOFTWARE/Clients/Lotus iNotes/DllPath points to it…
