Thanks this widget is great. A minimize button would be cool too.

Great widget! But that undo function just isn't enough. It will be way better to change a selected number by holding CTRL and clicking it, for example, and making it again a candidate (on that row and column). This is the only thing that's keeping me from using your widget, and I would really want to use your widget :). Oh, and i would love some statistics, like average time (on easy, hard, etc), or number of sudoku's played, or clicks clicked :).
G.

Your wish is my command.

I love this widget! I've recommended it to a bunch of people at work already. :) But please...give us 16x16!!! I need it to work the 16x16's that my coworker brings me from the newspaper (already filled in by him). I hope little Jimmy gets better soon! ;)

Sorry about that, there was a second bug in the random generator (it was returning numbers greater than one). Release 2.0.2 is in the approval process now, so the problem should be fixed (fingers crossed) soon.
