Hmmm, sounds like maybe somehow you've got the keyboard playalong wizard activated. Try looking under the "Play" menu and unchecking that item ("Wizard Playalong" - a little over halfway down the list).

I don't know if you also realize that when you type a letter for a chord, you don't see the letter in the chord box until you move the cursor again. So, if you go back to the default "C" chord with ZZjazz.sty default, use the arrow keys to move the cursor to the second measure (you'll click the right arrow twice). Now type "F". Then click the right arrow twice more to put the cursor in the third measure. You should now see the "F" chord in the second measure box on the chord grid. If you now type "G" (with the cursor in the third measure of the chord grid), you again won't see the "G" until you move the cursor again. So hit the right arrow, and now you'll see the "G". Does that make any sense at all? Does that help fix your problem?

Another thing to always try when the program is acting funny is "Return To Factory Settings" under the "Options" menu. I hope one of those suggestions helps. If not, post what happens here again, or you can always contact PG Music customer service - they are usually very responsive and helpful.

Keep at it. When you get this thing to work, you'll have a blast with it!
