Sudoku Portable

Routinely, Sudoku Portable produces puzzles that have non-unique solutions. Here's an example:
3,,1,,,,5,2,7
7,2,4,5,1,,,,6
,9,,2,7,8,3,,
9,5,6,7,3,,,8,
8,4,,,,2,6,,3
1,2,3,6,8,,,4,
4,6,9,8,5,7,,,
,,,9,2,1,4,,8
2,1,,3,4,,9,7,

The '1' and the '2' in R4C7, R4C9 & R7C7, R7C9 can be interchanged.

When I first started using Sudoku the Board was White with Black lettering just like the exe icon.
Some time in the past 2 or 3 weeks something changed it to green. I tried loading another one and trying it but I get the same thing.
So does anyone know how I can get back to the White board???
Thanks,

I often like to print a sudoku for the train (from various websites) ... it would be sooo much easier if i could print directly from the app like some other sudoku apps

The PC do not see my Pen drive anymore!!!!!!!
I just installed the Suduku Portable on my Transcend JF V30/4Gb. Pen drive.

Windows CAN NOT SEE the Drive now.

Properties of the Now Generic Disk, said File System unknown. Before it was FAT 32.

How I fix this. I have important files in this Pen Drive
Please Help

YOU CAN USE THE NUMERIC KEYPAD, TO INPUT POSSIBLE SOLUTIONS, WHEN YOU TURN ON CAPSLOCK.

I am an avid user of your Sudoku Portable. I understand you want to keep the application small so you have more than one solution to your puzzles. That is OK I just use this as brain candy. I would like to see an update that will automatically delete the small numbers in a square when a large number is selected. And I just mean the small numbers that correspond to the quadrant the number is in as well as the associated horizontal and vertical lines with that number. It would make solving the puzzle much easier and faster.

Initial numbers give multiple solutions.

I have to agree with a much echoed sentiment here that this application is not up-to-par with the quality of the other PortableApps.com applications--multiple solutions and guessing at numbers isn't "hard" it's just annoying.

Is anyone aware of better alternatives? Maybe a different source we could point John toward in making it portable? I haven't tried many Windows applications for this, but they mostly seem to be not free and not portable.

A couple of excellent, free, and open-source projects I have found for other platforms, both written in JAVA, are:

Hi,

I've just published a small script for the liveXP project from winbuilder which includes sudoku from portableapps.com

Also mentioned both developers on the credits section of the script and added a link to the respective portable app webpage on the description.

btw: There's a small typo on the sudoku description, look here: "Sudoku Portable is a an addictive"

You can find this script here:

there is a simple alternative to sudoku portable, which is already portable: http://stammel.net/denksport/sudoku_windows_en.html
