Within code insight the above setting is not remaining checked.

Every time I start up it is unticked, I have set my includes in Project Properties -> Properties -> Code Insight Includes but Code Insite still checks globally.

PhpED -> 4033
WinXP SP 2

I have to confirm, there is a problem with this checkbox. Its state is not saved.
Fixed version (build 4037) is already available to our customers per request.

Finally, it will be released as PHPED update pack #1.

Nice to know I'm not going mad and it was phped unchecking it each time.

honestly, this checkbox is not so important. You may leave it always unchecked.
It's intended to turn on additional filter to show in the code completion list only finctions/vartaibles/etc available in the included files.
Actually, it's not always possible to gather complete list of included files, in particular you might have something like include $mydir/$mylang."_f.php";
and phped has very little to do with it... And finally sometimes it's even better to see all the functions/classes/methods/consts etc than filtered.
So that checkbox while unchecked is good enough.
