#30 key-up on display change

[aetmos]

I'm writing a MIDlet game that, when a user clicks the
fire button in a certain area, the display is changed
fro mthe GameCanvas to a Form that displays a radio
question for the player to answer. This works fine in
the Sun emulator and on a real phone, but in the ME4SE
emulator, when the display returns to GameCanvas, the
fire key is stuck down for some reason until I hit
Enter again to clear it. I don't know if it matters or
not, but this with the applet version of ME4SE...I
haven't tried any other. I assume this is happening
because the GameCanvas is not receiving the key-up event.
