Particular Access Code Not Working

I created a gallery in preparation for an event yesterday together with a unique access code. The gallery was uploaded with photos today and set to publish. However the gallery is not accessible - "Gallery not found" comes up as the error message when entering the access code. The bug seems to be in the sequence of letters used - and after lots of experiments this morning I have found (by changing the access code on the gallery and then trying to access it):

The original code of sdreunion23 does NOT allow access

sdreunion does NOT allow access

sdreunio DOES allow access

sdreuniox DOES allow access

sdreuniox23 DOES allow access

sdreunio1234 DOES allow access

So, by adding the "n" on the end of "sdreunio" the system seems to not recognise the gallery. And it's clearly not the length or letters followed by numbers causing it. 

Never had this problem before - and i've been using Sytist since verion 1 (and it's previous incarnation)

There are certain words that are not allowed as passcode due to nefarious SQL code injection concerns.

I believe Union is one of them.

Thanks Trailboy. Can't find anything in the manual about it. Maybe it's buried in there somewhere!  However if this is the case, it would be useful if they could be disallowed when setting up the gallery! 

Perhaps that's intentional.  A check would be useful.

It would - as I do look a bit of a numpty in front of my customers this morning....  Looks like I need to manually check the validity in the future....
