No, basically Prowl and Howl are 2 different things, they are both
different Systems with different APIs, so this does not matter if you
have both with the same credentials, i don't think this could be a
reason but if you also have the Prowl Safari Extension installed, turn
it off for testing and try again just with Howl, it should work,,
basically if nothing happems inthe Extension it nearly always means
there was an error in the Howl API Request, i saw this while testing
the Extension, so there is bno error reporting included at the moment,
but if the Request to Howl fails, nothing happens,and while you only
need to setup the Username and Password, there is nothing the
Extension could do wrong i hope, an issue could cause this would be if
the characters in you Browser use a special KeyCode like UDF or
anything in this manner, well UDF-8 should work good, if not, let me
know which Keycode you use i can try to track the error down, or if
you like send me a mail at atxx [at]
me.com so i can try to send you a
special Extension version to determine the error or why you receive an
API Error, maybe we can track the error this way...the steps to figure
it out i would send you as well...
