Comment 5 for bug 515236

Wow! Great! Thanks for all the input.

Shame on me... I have to admit I pulled in this bugs when changing the order to be random.
Before that the order has always been the same (hard-coded) and I thought it might be better to be randomized (that's why I wrote the IRamdom Control). Sad but true: I have never been thinking about if it would still be solvable or not :/. And I must have been lucky to have played solvable puzzles when testing... again: shame on me :(.

Anyway, as it looks like you have all the needed code already made up in your mind it would be nice (and much faster) if you could help out here ;).
