wine users - Oct 2010 - How to edit/modify system32 exe files?

Hello,
I would like to try to edit/modify default values of winebrowser.exe (for
example with Reshacker) for it to open url and email addresses with Seamonkey...
(Trying to solve this problem => See my post)

Is it a wrong idea?

No, it's the correct idea and exactly the right place to change it.

You should really try it first form the command line. The proper option to use
is "-compose" not "-mail".

YESSSS!
Thank you very much vitamin for your precious help! :D 
All is now correct with seamonkey browser and mailer though I still have this in
my xerrs.log:
> wine: cannot find L"C:\\windows\\system32\\mailto:xxx at free.fr"
Is there something else to do for all being quite clean?

Cordialement!

Put it all back the way I told you in the beginning.
