VB2010 Hangman game

Attachment 114937
This is a simple game I made for my school. I hope to be able to deploy it on an interactive whiteboard eventually. We use hangman a lot to learn the alphabet and that is the reason I have included the option for single player or up to four teams.
Click "New Game and you use the letter buttons to choose the word(s) to be guessed. There is no reflection on screen for obvious reasons. At this stage, you can also choose the number of teams you want. Clicking "Finished" removes some of the command buttons and play begins.
Just click a letter to guess. If it is correct, it adds to the current team's score and if not, it adds to the hanged man.
When the game is over, all scores and the next team to play are preserved so you can play many consecutive games.
There is also a single player option without scores.
Further possible improvements:
Add sound, this is a must for my children.
Set team names

NOTE: If you decide to develop this game further, be aware you can NOT use Messagebox.Show. No idea why, but it seems to hang in the PictureBox.Paint sub.
