Have you tried setting the tabIndex property on each ComboBox?
If you've tried this, can you describe your problem in more detail (what
keys are you using, at what point do you hit the problem, etc) and post
a code sample?
No, I have not set tabIndex, and when I test with a tabIndex, it doesn't works better.
My problem happens when I want to choose a date with my keypad. If I want to choose 4 for th day of the birthdate, i can choose with my mouse, using shift and the number on the keyboard, but it never works with the keypad.
I don't have any code special, it is just a combo-box.
I have find a response.
It is a bug, adobe had correct it on the latest version 3.4.0.
I have test and it works.
If it could help someone ^^
