Using Windows LAF, I noticed this behaviour, I have a combo editor for a table that is within a Frame
when editing a value, if the combo pop up goes further than the Frame, the selection is lost, no value
can be selected. This bug is very annoying to customers, since my product includes an editor that they
 use, and I can't change the screen sizes to be able to avoid the bug...

With JDK1.4.0-beta3, the bug is reproducible even if the combo popup falls within the Frame.

In Metal LAF, with 1.3.1_01 the test case works fine but with 1.4.0-beta3 the problem is reproducible if the combo popup goes outside the Frame.
