Problems:

1. When Frame becomes visible, choice number 1 in the (1,1) cell
of the grid does not get focus automatically, but it does get focus
under the same circumstances on WinNT.

2. When focus is on Choice number 1 and Frame is resized,
this choice looses focus. Focus should be returned to
Choice number 1 after the resize but it isn't. It is
however returned to Choice number 1 on winNT under the same circumstances.

3. Notice that all of the TextFields return false from isFocusTraversable()
indicating that they should not get focus under keyboard traversal
using TAB or SHIFT-TAB. If you keep the mouse over the
Frame, the traversal using keyboard works properly.
If you move mouse out of the Frame, keyboard traversal
gets REALLY MESSED UP.
  a. on TAB, the TextField in the cell (0,2) to the right
of Choice number 2 gets focus but is shouldn't. No other TextFields
get focus on subsequent TAB presses. So the only components
that will be traversed are the two Choices and the TextField in the
cell (0,2).
  b . on SHIFT-TAB the TextField in the very last cell (bottom
right corner of grid) will receive focus. No other TextFields
get focus on subsequent SHIFT-TAB presses. SO now the components
traversed using SHIFT-TAB are the two choices and the
Text Field in the cell described above.

None of this happens on WinNT.
I am running Solaris 2.5 on Sparc station 5 with
DCE (Common Desktop Environment) window manager.
