Arrays, recursion and crashes?

[David Bovill]

Fixing the array keys to use simple numeric strings (hashes for now) rather
than keys based on the names of controls fixes the crashes - so the problem
is not with call-by-reference or recursion. I'll try different naming
schemse to see what sort of names create the crash - I assume it is some
sort of invisible char as there is nothing I can see in the names that
should cause a problem.
