Comment 23 for bug 1321512

Ah, i see... that is very interesting! So the problem appears to be that windows doesn't generate a uniqueid each time when using the uniqueid function.

In that case, either of your solutions would appear to work fine - there is a built in Kit method that could be used instead

Kit::uniqueId();

I will target and fix this for 1.7.0-alpha2.

Thanks for the debug while I was asleep! :)
