Logic 9 not responding to computer keyboard correctly

Question

In Logic Pro 9, dialog boxes (such as the Save As) do not receive the computer keyboard strokes. Instead, Logic processes them as key commands. This even though the dialog box has the focus and the mouse can select fields and highlight their entries. Very strange. Typing sometimes works correctly, but usually not. And once it doesn't, even if it did earlier, I must reboot to have a hope to fix it.
This happens with the Save As dialog, and with any other dialog box that has typeable fields.
I am current on Logic 9 and Mac OS X.

Answer 1

Okay, I figured out enough to work around it and to fix it without having to restart Logic or reboot. I can't work out the exact chain of events to reproduce it, but here are the important things to do if it happens. And BTW, it happens to me on the File>Bounce dialog box, not the File>Save As dialog. I assume this is actually a bug.
1.) Sometimes the key commands do get disabled, and none of them work. So you have to go to Logic Pro > Preferences > Key Commands and select Options > Initialize. Just like immo says.
2.) Sometimes, this isn't enough. In which case, do two more things...
3.) Be sure the Arrange subwindow has the focus (ie, the white band around the window), and
4.) Be sure the first time you try to enter anything into the Bounce dialog window it is in the Save As filename field, not the End measure numeric field (or any other). If I try to enter any keyboard values into any other field first, I can't and I also can't then enter anything into the Save As field either. I then just have to start over again with the key command initialization step and so on.
These workarounds combined have allowed me to always recover from this issue. Though I do have to do them multiple times in a session, at least when I'm bouncing down.
Thanks everyone for your input and help!
Best,
