Your conf.xml is out of date.

I just logged in with a totally new browser instance.  Still got the 
notice.  I went and regenerated my IMP configuration.  Here it is:

I don't see any line that starts with $conf['notepad'].

You didn't log in again with a clean session after the config update.

Not bogus.  I just updated my configs for both Horde and IMP, and it 
still shows the message.



My imp/config/conf.xml is dated 29-Jul-2005.  Is that right?

Update your configurating after updating IMP.
